Handling common JavaScript problems - Learn web development
these days, most cross-browser javascript problems are seen: when poor-quality browser-sniffing code, feature-detection code, and vendor prefix usage block browsers from running code they could otherwise use just fine.
... declaring strict mode at the top of your javascript code causes it to be parsed with a stricter set of rules, meaning that more warnings and errors will be thrown, and some things will be disallowed that would otherwise be acceptable.
... ui libraries: provide methods for implementing complex ui features that would otherwise be challenging to implement and get working cross browser, for example foundation, bootstrap, and material-ui (the latter is a set of components for use with the react framework).

...otherwise it will return to monitoring mode.

JSAPI User Guide
otherwise, the gc will free the memory occupied by those values, leading to a probable crash the next time your program tries to use them.
... note that you do not need to call js_initclass to make a new instance of that class—otherwise there would be a chicken-and-egg problem making the global object—but you should call js_initclass if you require a constructor function for script authors to call via new, and/or a class prototype object (myclass.prototype) for authors to extend with new properties at run time.
...or a js object that mirrors data and functions that already exist in the application may provide an object-oriented interface to c code that is not otherwise, strictly-speaking, object-oriented itself.

JS_CheckAccess
otherwise, if obj's class has a non-null jsclass.checkaccess callback, then it is called to perform the check.

JS_NewGlobalObject
otherwise it returns null.
...otherwise, callers should pass dontfireonnewglobalhook, which means that they are responsible for invoking js_fireonnewglobalobject upon successfully creating the global.
...but otherwise, callers must take care to fire the hook exactly once before compiling any script in the global's scope (we have assertions in place to enforce this).

Web Replay
this requires using the same build of firefox and a reasonably similar version of the operating system; otherwise the tab will probably crash.
... inter-thread non-determinism is handled by first assuming the program is data race free: shared memory accesses which would otherwise race are either protected by locks or use apis that perform atomic operations.
... this mechanism requires intercepting mmap (or similar low level allocation functions) so that any newly addressable memory is known — anonymous mappings would not otherwise be intercepted or included in the recording, as heap allocation is non-deterministic while replaying.

Handling Mozilla Security Bugs
this work is separate from the work of developers adding new security features (cryptographically-based or otherwise) to mozilla, although obviously many of the same people will be involved in both sets of activities.
... other participants besides the permanent security bug group members described above, there are two other categories of people who may participate in security bug group activities and have access to otherwise-confidential security bug reports: a person who reports a security bug will have continued access to all bugzilla activities associated with that bug, even if the bug is marked "security-sensitive." any other persons may be given access to a particular security bug, by someone else (who does have access) adding them to the cc list for that bug.
...however, we do expect members of the group: not to disclose security bug information to others who are not members of the mozilla security bug group or are not otherwise involved in resolving the bug.

Getting Started Guide
as described above, and unless you tell it otherwise, an nscomptr addrefs when you assign in to it.
... void f( nscomptr<t> ) don't pass an nscomptr by value this practice is wasteful, but not otherwise harmful.
... void f( const nscomptr<t>& ) don't pass an nscomptr by const reference exactly as the signature above, this practice is wasteful, but not otherwise harmful, and has the same impact as passing an nscomptr by value if the caller only supplied a raw pointer.

Declaring and Using Callbacks
the return type of the javascript callback must match the return type declared, otherwise js-ctypes will throw an error saying "unexpected return type".
... var myfunctypedeclaration = ctypes.functiontype(ctypes.default_abi, ctypes.bool, [ctypes.int, ctypes.voidptr_t]); function myjscallback(cint, cptr) { return true; // as the return of the functiontype was ctypes.bool we must make our javascript callback return bool otherwise js-ctypes will throw error saying unexpected type return } var myccallback = myfunctypedeclaration.ptr(myjscallback); example 2 this callback that returns void and no arguments.
... var myfunctypedeclaration = ctypes.functiontype(ctypes.default_abi, ctypes.void_t, []); function myjscallback() { return undefined; // as the return of the functiontype was ctypes.void_t we must return undefined or dont return at all otherwise js-ctypes will throw an error saying unexpected type } var myccallback = myfunctypedeclaration.ptr(myjscallback); using callbacks since callbacks are function pointers in c, js-ctypes has special handling for function pointer types.

Establishing a connection: The WebRTC perfect negotiation pattern - Web APIs
the best thing about perfect negotiation is that the same code is used for both the caller and the callee, so there's no repetition or otherwise added levels of negotiation code to write.
...otherwise, we set srcobject to the stream at index 0 in the streams array.
...otherwise, we drop the error, ignoring it, since it doesn't matter in this context.

Viewpoints and viewers: Simulating cameras in WebXR - Web APIs
perspective, properly applied to the objects in a scene, can take a scene that would otherwise look as flat as a typical 2d screen and make it pop as if it were truly 3d.
... but the location isn't enough to describe an object in 3d space because an object's state in space isn't only about its location, but about its rotation or facing direction, otherwise known as its orientation.

Using IIR filters - Web APIs
as well as this, if your audio graph needed a highpass and a bandpass filter within it, you could just use one iir filter node in place of the two biquad filter nodes you would otherwise need for this.
... when setting our coefficients, the feedforward values can't all be set to zero, otherwise nothing would be sent to the filter.
... something like this is acceptable: let feedforward = [0.00020298, 0.0004059599, 0.00020298]; our feedback values cannot start with zero, otherwise on the first pass nothing would be sent back: let feedbackward = [1.0126964558, -1.9991880801, 0.9873035442]; note: these values are calculated based on the lowpass filter specified in the filter characteristics of the web audio api specification.

Window: popstate event - Web APIs
these methods and their corresponding events can be used to add data to the history stack which can be used to reconstruct a dynamically generated page, or to otherwise alter the state of the content being presented while remaining on the same document.
...he moment when the new document state is already fully in place, a zero-delay settimeout() method call should be used to effectively put its inner callback function that does the processing at the end of the browser event loop: window.onpopstate = () => settimeout(dosomething, 0); when popstate is sent when the transition occurs, either due to the user triggering the browser's "back" button or otherwise, the popstate event is near the end of the process to transition to the new location.
... if new-entry has serialized state information saved with it, that information is deserialized into history.state; otherwise, state is null.

Window.showModalDialog() - Web APIs
options is an optional string specifying window ornamentation for the dialog, using one or more semicolon delimited values: syntax description center: {on | off | yes | no | 1 | 0 } if on, yes, or 1, the dialog window is centered on the desktop; otherwise it's hidden.

Privacy and the :visited selector - CSS: Cascading Style Sheets
only the following styles can be applied to visited links: color background-color border-color (and its sub-properties) column-rule-color outline-color the color parts of the fill and stroke attributes in addition, even for the above styles, you won't be able to change the transparency between unvisited and visited links, as you otherwise would be able to using rgba(), hsla(), or the transparent keyword.
...you need to specify a different value, otherwise changes on :visited won't apply.
... colors that are otherwise transparent will fail to appear if styled in a :visited selector.

overflow-wrap - CSS: Cascading Style Sheets
the overflow-wrap css property applies to inline elements, setting whether the browser should insert line breaks within an otherwise unbreakable string to prevent text from overflowing its line box.
... anywhere to prevent overflow, an otherwise unbreakable string of characters — like a long word or url — may be broken at any point if there are no otherwise-acceptable break points in the line.
... break-word the same as the anywhere value, with normally unbreakable words allowed to be broken at arbitrary points if there are no otherwise acceptable break points in the line, but soft wrap opportunities introduced by the word break are not considered when calculating min-content intrinsic sizes.

repeat() - CSS: Cascading Style Sheets
otherwise, as its minimum track sizing function, and taking grid-gap into account.
...otherwise, if the grid container has a definite minimal size in the relevant axis, the number of repetitions is the smallest possible positive integer that fulfills that minimum requirement.
... otherwise, the specified track list repeats only once.

Creating a cross-browser video player - Developer guides
ie9 will only use the specified poster image in this way if preload="none" is set; otherwise, it will take the first still of the video and display that instead.
...otherwise the video must be playing, so it is paused using the pause() method.
... fullscreen the fullscreen api should be straight forward to use: the user clicks a button, if the video is in fullscreen mode: cancel it, otherwise enter fullscreen mode.

<input>: The Input (Form Input) element - HTML: Hypertext Markup Language
alt valid for the image button only, the alt attribute provides alternative text for the image, displaying the value of the attribute if the image src is missing or otherwise fails to load.

... :disabled any currently disabled element that has an enabled state, meaing it otherwise could be activated (selected, clicked on, typed into, etc.) or accept focus were it not disabled.

HTTP headers - HTTP
timing-allow-origin specifies origins that are allowed to see values of attributes retrieved via features of the resource timing api, which would otherwise be reported as zero due to cross-origin restrictions.
... x-download-options the x-download-options http header indicates that the browser (internet explorer) should not display the option to "open" a file that has been downloaded from an application, to prevent phishing attacks as the file otherwise would gain access to execute in the context of the application.
...the file may define a policy to grant clients, such as adobe's flash player, adobe acrobat, microsoft silverlight, or apache flex, permission to handle data across domains that would otherwise be restricted due to the same-origin policy.

Numbers and dates - JavaScript
the first statement creates a variable temp, assigning it a value using a conditional expression; if hour is greater than 12, (hour - 12), otherwise simply hour, unless hour is 0, in which case it becomes 12.
...if the value of minute is less than 10, the conditional expression adds a string with a preceding zero; otherwise it adds a string with a demarcating colon.
... finally, a conditional expression appends "p.m." to temp if hour is 12 or greater; otherwise, it appends "a.m." to temp.

... description the reflect.getownpropertydescriptor method returns a property descriptor of the given property if it exists in the target object, undefined otherwise.

String - JavaScript
method 1 you can use the + operator to append multiple strings together, like this: let longstring = "this is a very long string which needs " + "to wrap across multiple lines because " + "otherwise my code is unreadable." method 2 you can use the backslash character (\) at the end of each line to indicate that the string will continue on the next line.
... make sure there is no space or any other character after the backslash (except for a line break), or as an indent; otherwise it will not work.
... that form looks like this: let longstring = "this is a very long string which needs \ to wrap across multiple lines because \ otherwise my code is unreadable." both of the above methods result in identical strings.

TypedArray.prototype.every() - JavaScript
return value true if the callback function returns a truthy value for every array element; otherwise, false.
...otherwise, if callback returned a true value for all elements, every will return true.

... otherwise javascript attempts to convert non-numeric types to numeric values: boolean values true and false are converted to 1 and 0 respectively.
... otherwise the values are compared as numeric values.

Web video codec guide - Web media technologies
if the codec converts the media into an internal pixel format, or otherwise represents the image using a means other than simple pixels, the format of the original image doesn't make any difference.
...this means that any errors or artifacts will compound over time, resulting in glitches or otherwise strange or unexpected deviations in the image that linger for a time.
...otherwise, you should probably consider a different codec.

The "codecs" parameter in common media types - Web media technologies
otherwise, the video data is entirely in the y plane and is therefore monochromatic.
...if both of those are 1, the third is the value of chroma_sample_position; otherwise, the third digit is always 0.

the high contrast theme can be toggled dynamically with leftalt+leftshift+printscreen expose the spi_getscreenreader flag to xml/scripts so that apps can alter behavior use system highlight color where possible for item selection, but never use that exact color in more than 1 place at a time, otherwise screen reader will read everything with that color whenever highlight changes pay attention to spi_getcaretwidth for the correct width of the caret pay attention to 'route mouse pointer to default button' setting it's possible that the user wants mnemonics hidden except when the alt key is pressed.
...kes do the right thing msaa support (default state) links enter key activates link (thus default button no longer shows dark border when link is focused) msaa support, including linked and traversed states, and accessible value that holds destination url text fields - single and multiple line it's probably best to use native widgets for these, otherwise accessibility support will be quite difficult tab should always focus the next item, not insert a tab, unless there's a really good reason and another way to navigate always use system selection color, otherwise screen reader won't read the text make sure the caret is never blinking when focus is not in text field handle standard editing keys, such as arrow keys, home, end...

entities are frequently used to display reserved characters (which would otherwise be interpreted as html code), and invisible characters (like non-breaking spaces).

Fuzz testing - MDN Web Docs Glossary: Definitions of Web-related terms
fuzzing is a technique for testing software using automated tools to provide invalid or unexpected input to a program or function in a program, then checking the results to see if the program crashes or otherwise acts inappropriately.

Scroll container - MDN Web Docs Glossary: Definitions of Web-related terms
the scroll container allows the user to scroll through parts of the overflow region that would otherwise be clipped and hidden from view.

Syntax - MDN Web Docs Glossary: Definitions of Web-related terms
code must have correct syntax in order to compile correctly, otherwise a syntax error occurs.

XInclude - MDN Web Docs Glossary: Definitions of Web-related terms
); var a = []; for(var k = 0; k < xpathresult.snapshotlength; k++) { a[k] = xpathresult.snapshotitem(k); } responsenodes = a; } else { // otherwise, the response must be a single well-formed document response responsenodes = [response.documentelement]; // put in array so can be treated the same way as the above } // prepend any node(s) (as xml) then remove xinclude for (j=0; j < responsenodes.length ; j++) { ...

otherwise it is mandatory.

The HTML5 input types - Learn web development
the browser will report an error if no protocol (such as http:) is entered, or if the url is otherwise malformed.

Styling web forms - Learn web development
take the following example: to position the legend in this manner, we used the following css (other declarations removed for brevity): fieldset { position: relative; } legend { position: absolute; bottom: 0; right: 0; } the <fieldset> needs to be positioned too, so that the <legend> is positioned relative to it (otherwise the <legend> would be positioned relative to the <body>.) the <legend> element is very important for accessibility — it will be spoken by assistive technologies as part of the label of each form element inside the fieldset — but using a technique like the one above is fine.

CSS basics - Learn web development
otherwise, the styling won't change the appearance of the html.

Installing basic software - Learn web development
windows: firefox, chrome, opera, internet explorer, microsoft edge, brave (windows 10 comes with edge by default; if you have windows 7 or above, you can install internet explorer 11; otherwise, you should install an alternative browser).

almost any web content can be converted to a link so that when clicked or otherwise activated the web browser goes to another web address (url).

Document and website structure - Learn web development
take care to use them only when there is no better semantic solution and try to reduce their usage to the minimum otherwise you'll have a hard time updating and maintaining your documents.

in all cases, you must provide an <img> element, with src and alt, right before </picture>, otherwise no images will appear.

Video and audio content - Learn web development
timed descriptions text which should be spoken by the media player in order to describe important visuals to blind or otherwise visually impaired users.

Fetching data from the server - Learn web development
add this next: request.responsetype = 'text'; fetching a resource from the network is an asynchronous operation, meaning that you have to wait for that operation to complete (e.g., the resource is returned from the network) before you can do anything with that response, otherwise, an error will be thrown.

Manipulating documents - Learn web development
make sure you don't get these mixed up, otherwise it won't work.

Third-party APIs - Learn web development
}) to check whether each article has any images associated with it (some stories don't.) we display the first image only if it exists (otherwise an error would be thrown).

Handling text — strings in JavaScript - Learn web development
try the following (we are using the typeof operator to check whether the variable is a number or a string): let mydate = '19' + '67'; typeof mydate; if you have a numeric variable that you want to convert to a string but not change otherwise, or a string variable that you want to convert to a number but not change otherwise, you can use the following two constructs: the number object converts anything passed to it into a number, if it can.

Storing the information you need — Variables - Learn web development
when you give a variable a string value, you need to wrap it in single or double quote marks; otherwise, javascript tries to interpret it as another variable name.

JavaScript object basics - Learn web development
try these in the js console: person.name.first person.name.last important: at this point you'll also need to go through your method code and change any instances of name[0] name[1] to name.first name.last otherwise your methods will no longer work.

Object-oriented JavaScript for beginners - Learn web development
the basic idea of oop is that we use objects to model real world things that we want to represent inside our programs, and/or provide a simple way to access functionality that would otherwise be hard or impossible to make use of.

Object building practice - Learn web development
along the way we'll make use of some nifty objects, and show you a couple of nice techniques like bouncing balls off walls, and checking whether they have hit each other (otherwise known as collision detection).

Multimedia: video - Learn web development
otherwise, it wastes a lot of bandwidth.

Client-Server Overview - Learn web development
the information is otherwise similar to that for the response to a get request.

Introduction to the server side - Learn web development
client-side web frameworks simplify layout and presentation tasks while server-side web frameworks provide a lot of “common” web server functionality that you might otherwise have to implement yourself (e.g.

Website security - Learn web development
the process of modifying user data so that it can't be used to run scripts or otherwise affect the execution of server code is known as input sanitization.

Getting started with Ember - Learn web development
the templating language is used to make build and runtime optimizations that otherwise wouldn't be possible.

Ember app structure and componentization - Learn web development
testing is outside the scope of this tutorial, although generally testing should be implemented as you develop, rather than after, otherwise it tends to be forgotten about.

Advanced Svelte: Reactivity, lifecycle, accessibility - Learn web development
and that makes sense, because otherwise svelte would be aware of the inner workings of the foreach() method; the same would therefore be true for any method attached to any object or array.

Vue conditional rendering: editing existing todos - Learn web development
it's important to note that v-else and v-else-if blocks need to be the first sibling of a v-if/v-else-if block, otherwise vue will not recognize them.

Creating our first Vue component - Learn web development
note that you need to use the v-bind syntax, because otherwise true is passed as a string.

Getting started with Vue - Learn web development
if you like these settings over the existing presets and want to use them again, type y , otherwise type n.

Rendering a list of Vue components - Learn web development
you are no longer using uniqueid, so you need to remove the import uniqueid from 'lodash.uniqueid'; line, otherwise your app will throw an error.

Handling common accessibility problems - Learn web development
element relationships and context there are certain features and best practices in html designed to provide context and relationships between elements where none otherwise exists.

Setting up your own test automation environment - Learn web development
for example if you load a new page, you'll want to wait for the page's dom to finish loading before you try to interact with any of its elements, otherwise the test will likely fail.

this remote location needs to be added to our local git repository before we can push it up there, otherwise it won't be able to find it.

Client-side tooling overview - Learn web development
this is one reason we wrote this series of articles, to hopefully provide that first step that is hard to find otherwise.

Package management basics - Learn web development
parcel expects an index.html and an index.js file to work with, but otherwise it is very unopinionated about how you structure your project.

Mozilla accessibility architecture
in that case we also override ::getaccnextsibling(), ::getaccprevioussibling() for the dom-less children; otherwise they do not know how to find each other.

Software accessibility: Where are we today?
otherwise, screen magnification programs may be used, which allow zooming in to portions of the screen, while following the mouse or the current focus.

A bird's-eye view of the Mozilla framework
otherwise it returns null.

Chrome registration
each line is parsed individually; if the line is parsable the chrome registry takes the action identified by that line, otherwise the chrome registry ignores that line (and prints a warning message in the runtime error console).

Simple SeaMonkey build
# on windows, be sure to use mozmake instead of make, otherwise parallel building will break.

mach
another possible reason: mach gives you an error, while running, say bootstrap.py directly (that is to type in a bash shell: python2 ./bootstrap.py enter-key ) in an otherwise empty ..../subdir/ may work for you!

Multiple Firefox profiles
otherwise, enter a space character followed by --profilemanager.

Cross Process Object Wrappers
this makes the cpow call much safer than it would otherwise be.

Frame script loading and lifetime
for example, from bootstrap.js: services.mm.addmessagelistener( 'my-addon-id', { receivemessage: function() { console.log('incoming message from frame script:', amsg.data); } }, true // must set this argument to true, otherwise sending message from framescript will not work during and after the unload event on the contentmessagemanager triggers ); then in your frame script, listen for the unload event of the message manager (which is the global this), and sending a message.

Performance best practices for Firefox front-end engineers
otherwise, we're doing a cheap look-up of cached information.

Using the Browser API
we do this with the following function, which runs the htmliframeelement.stop() method to stop the page loading if the button is displaying a cross, and the htmliframeelement.reload() method to reload the page otherwise.

CSS -moz-bool-pref() @supports function
syntax -moz-bool-pref( <string> ) parameters <string> the preference name returns evaluates to true if the preference is enabled, false otherwise.

otherwise, gecko can replace the charcode with an ascii character.

HTML parser threading
otherwise it has failed.

Geckoview-Junit Tests
before running tests, install the androidtest apk on your device; otherwise, 'mach geckoview-junit' will offer to install it.

How to get a stacktrace with WinDbg
.logopen /t c:\temp\firefox-debug.log .childdbg 1 .tlist sxn gp lm if you see firefox.exe listed in the output from .tlist more than once, then you are already running the application and need to close the running instance first before you start debugging, otherwise you won't get useful results.

IPDL Tutorial
message implementations should return false from a message implementation if the data is corrupted or otherwise malformed.

Implementing Download Resuming
otherwise, call resumeat with the desired start position, and the previously stored entity id.

Addon
if possible the uninstall will happen immediately, otherwise it will wait until the next application restart.

Add-on Repository
issearching boolean true if a search is currently in progress; otherwise false.

AsyncShutdown.jsm
return value returns true if a blocker has been removed, or false otherwise.

DeferredTask.jsm
bool ispending(); return value returns true if pending, false otherwise.

Dict.jsm
return value true if the specified key is in the dictionary, otherwise false.

Interfacing with the Add-on Repository
otherwise, the addoninstall object's install() method is called to install the add-on.

JavaScript OS.Constants
debug set to true on debug build configurations, non-existent otherwise.

PerfMeasurement.jsm
otherwise, it returns false.

Examples
always wrap that function in a try catch and make that catch return promise.reject(ex) otherwise it will not trigger the rejection function of the promise.then.

Promise
for example, the os.file.exists function returns a promise that will eventually fulfill with a boolean: promise<boolean> exists(string path); the rejection reason may be specified separately in the function's documentation, and is considered to be an error object unless otherwise specified.

PromiseWorker.jsm
in summary, from a worker file, data can only be sent back as a response to a request from the main thread, it is not possible for a worker to send data to the main thread otherwise, this is a key difference between promiseworker worker file and all other types of workers.

XPCOMUtils.jsm
otherwise, null is returned.

Localizing with Koala
for example: c:\users\stas> cd c:\mozilla\l10n\locale\x-testing c:\mozilla\l10n\locale\x-testing> rmdir 3.6 c:\mozilla\l10n\locale\x-testing> hg clone http://bitbucket.org/mozillal10n/x-testing 3.6 otherwise, it's a good idea to create your local repository in order to be able to track changes you make to the localization files.

QA phase
if you're using koala, this should be located at /path/to/your/koala.project/locale/3.6/x-testing, otherwise, it should be located at /path/to/your/working_dir/l10n_base/x-testing.

Release phase
otherwise, in order to be able to make any changes to the localization files, you will need to clone the repository on your local machine and work in the local clone.

Creating localizable web applications
otherwise, php will treat $s as a regular variable, instead of parsing the whole %1$s formatting symbol.

Basics
f ( 4 ) ( η ) , a ≤ η ≤ b | x | = { - x if x < 0 x otherwise you can also typeset 2d mathematical constructs such as matrices.

MathML Demo: <mtable> - tables and matrices
this would be pretty hard to obtain otherwise.

Using the viewport meta tag to control layout on mobile browsers
otherwise, the relationship between css pixels and device pixels depends on the current zoom level.

Mozilla Port Blocking
"access to the port number given has been disabled for security reasons." "establishing a connection to an unsafe or otherwise banned port was prohibited" "0x804b0013 (ns_error_port_access_not_allowed)" if your product or web site uses a port which is blocked by mozilla's default port blocking rules, you can either change the port of your service to a unblocked value (recommended if possible) or ask your mozilla users to enable the port.

Mozilla Web Developer FAQ
otherwise, finding out the intentions of each particular author would require psychic abilities which can’t be implemented in software.

Mozilla Web Services Security Model
the from attribute otherwise gives a url to match, which may contain up to two asterisks (*) that match any characters in the url.

Mozilla Quirks Mode Behavior
maybe (firefox 3) when computing the minimum intrinsic width of an inline flow directly in a table cell (no blocks in between), it is assumed that it is not possible to break before and after an image (when otherwise it would be).

Intel Power Gadget
the api is otherwise unlikely to be of interest to mozilla developers.

Refcount tracing and balancing
this can help remove some of the clutter from an otherwise noisy tree.

tools/power/rapl
otherwise, it will fail with an error message explaining this requirement.

Productization guide
the second purpose (demonstrate certain features of the product) is equally important: by providing these default services, we demonstrate particular features of the product, the ones which otherwise wouldn’t be as discoverable.

NSPR Poll Method
otherwise ((new_flags & out_flags) is 0), you should do the following.

PRBool
otherwise, use prbool for variables and parameter types.

PRFileDesc
otherwise, you use functions such as pr_open and pr_newtcpsocket to obtain a file descriptor, which you should treat as an opaque structure.

PR_ASSERT
when the result is zero (false) the application terminates; otherwise the application continues.

PR_CLIST_IS_EMPTY
description pr_clist_is_empty returns a non-zero value if the specified list is an empty list, otherwise returns zero.

PR_GetErrorTextLength
otherwise, the value returned is sufficient to contain the error text currently available.

PR_GetSpecialFD
otherwise, pr_getspecialfd returns null and sets the error to pr_invalid_argument_error.

PR_Interrupt
otherwise, pr_failure.

PR_LOG_TEST
possible values are: pr_log_none = 0 pr_log_always = 1 pr_log_error = 2 pr_log_warning = 3 pr_log_debug = 4 pr_log_notice = pr_log_debug pr_log_warn = pr_log_warning pr_log_min = pr_log_debug pr_log_max = pr_log_debug returns pr_true when logging is enabled for the given module and level, otherwise pr_false.

PR_STATIC_ASSERT
when the result is zero (false) program compilation will fail with a compiler error; otherwise compilation completes successfully.

PR_SetErrorText
otherwise the text is assumed to be the length specified and to possibly include null characters (as might occur in a multilingual string).

PR_SetLogFile
otherwise, pr_false.

PR_StringToNetAddr
otherwise, use of anything other than ipv4 dotted notation results in an error.

NSS Code Coverage
if file was tested, link points to annotated source file (in tcov directory), otherwise to original source file (cvs directory).

NSS 3.34 release notes
prbool resumed is pr_true when the session is resumed, and pr_false otherwise.

NSS API Guidelines
this means if an arena is specified (non-null), it is used, otherwise (null) the routine uses the heap.
