PR_NewTCPSocket
syntax #include <prio.h> prfiledesc* pr_newtcpsocket(void); returns the function returns one of the following values: upon successful completion, a pointer to the prfiledesc object created for the newly opened ipv4 tcp socket.
...pr_newtcpsocket creates a new ipv4 tcp socket.
... see also pr_newtcpsocket is deprecated because it is hardcoded to create an ipv4 tcp socket.

PR_NewUDPSocket
syntax #include <prio.h> prfiledesc* pr_newudpsocket(void); returns the function returns one of the following values: upon successful completion, a pointer to the prfiledesc object created for the newly opened udp socket.
... pr_newudpsocket creates a new udp socket.
... see also pr_newudpsocket is deprecated because it is hardcoded to create an ipv4 udp socket.

PR_NewLock
syntax #include <prlock.h> prlock* pr_newlock(void); returns the function returns one of the following values: if successful, a pointer to the new lock object.
... description pr_newlock creates a new opaque lock.

PR_NewThreadPrivateIndex
syntax #include <prthread.h> prstatus pr_newthreadprivateindex( pruintn *newindex, prthreadprivatedtor destructor); parameters pr_newthreadprivateindex has the following parameters: newindex on output, an index that is valid for all threads in the process.
... description if pr_newthreadprivateindex is successful, every thread in the same process is capable of associating private data with the new index.

PR_NEW
syntax #include <prmem.h> _type * pr_new(_struct); parameter _struct the name of a type.

PR_NEWZAP
syntax #include <prmem.h> _type * pr_newzap(_struct); parameter _struct the name of a type.

PR_NewCondVar
syntax #include <prcvar.h> prcondvar* pr_newcondvar(prlock *lock); parameter pr_newcondvar has one parameter: lock the identity of the mutex that protects the monitored data, including this condition variable.

PR_NewLogModule
syntax #include <prlog.h> prlogmoduleinfo* pr_newlogmodule(const char *name); parameters the function has this parameter: name the name to be assigned to the prlogmoduleinfo structure.

PR_NewMonitor
syntax #include <prmon.h> prmonitor* pr_newmonitor(void); returns the function returns one of the following values: if successful, a pointer to a prmonitor object.

PR_NewPollableEvent
syntax nspr_api(prfiledesc *) pr_newpollableevent( void); parameter none.

Nonblocking IO In NSPR
in nspr, a new socket returned by <tt>pr_newtcpsocket()</tt> or <tt>pr_newudpsocket()</tt> is always created in blocking mode.
... one can make the new socket nonblocking by using <tt>pr_setsockopt()</tt> as in the example below (error checking is omitted for clarity): <tt>prfiledesc *sock;</tt> <tt>printn optval = 1;</tt> <tt>sock = pr_newtcpsocket();</tt> /* * make the socket nonblocking */ pr_setsockopt(sock, pr_sockopt_nonblocking, &optval, sizeof(optval)); programming constraints there are some constraints due to the use of nt asynchronous i/o in the nspr.

Logging
log types and variables two types supporting nspr logging are exposed in the api: prlogmoduleinfo prlogmodulelevel two environment variables control the behavior of logging at execution time: nspr_log_modules nspr_log_file logging functions and macros the functions and macros for logging are: pr_newlogmodule pr_setlogfile pr_setlogbuffering pr_logprint pr_logflush pr_log_test pr_log pr_assert pr_assert pr_static_assert (new in nspr 4.6.6xxx this hasn't been released yet; the number is a logical guess) pr_not_reached use example the following sample code fragment demonstrates use of the logging and debugging aids.
... before running the compiled program, set the environment variable nspr_log_modules to userstuff:5 static void userlogstuff( void ) { prlogmoduleinfo *mylm; printn i; pr_static_assert(5 > 4); /* nspr 4.6.6 or newer */ mylm = pr_newlogmodule( "userstuff" ); pr_assert( mylm ); pr_log( mylm, pr_log_notice, ("log a notice %d\n", 999 )); for (i = 0; i < 10 ; i++ ) { pr_log( mylm, pr_log_debug, ("log debug number: %d\n", i)); pr_sleep( 500 ); } pr_log( mylm, pr_log_notice, "that's all folks\n"); } /* end userlogstuff() */ see also nspr logging reference ...

Monitors
monitor type with the exception of pr_newmonitor, which creates a new monitor object, all monitor functions require a pointer to an opaque object of type prmonitor.
... pr_newmonitor creates a new monitor.

NSPR LOG MODULES
syntax modulename:level[, modulename:level]* modulename is the name specified in a pr_newlogmodule call or one of the handy magic names listed below.
... description specify a modulename that is associated with the name argument in a call to pr_newlogmodule and a non-zero level value to enable logging for the named modulename.
