nsastring& as the domstring comes in from js as utf-16.

Debugging on Windows
for xpcom strings (the "external" string api) you can use the following values: ;; mozilla (1.9) ; internal strings
nsastring_internal=<mdata,su>, length=<mlength,u> nsacstring_internal=<mdata,s>, length=<mlength,u> ; xpcom strings
nsastring=<nsstringcontainer.v,su>, length=<nsstringcontainer.d1,u> nsacstring=<nscstringcontainer.v,s>, length=<nscstringcontainer.d1,u> nsstringcontainer=<v,su>, length=<d1,u> nscstringcontainer=<v,s>, length=<d1,u> there is a more extensive version of this file in progress in autoexpforv...

Secure Development Guidelines
using the mozilla api mozilla c++ style strings are less prone to buffer overflows and 0-termination issues every string derived from the abstract base class
nsastring common read-only methods length() isempty() equals() common methods for modifying the string assign() append() insert() truncate() checking return values often causes problems return value not handled certain cases not handled or interpreted incorrectly double meaning malloc() can return a pointer or null, but null by itself is a valid address ...

Detailed XPCOM hashtable guide
the mozilla codebase already contains hash functions for most key types, including narrow and wide strings, pointers, and most binary data: void* (or nsisupports*) cast using ns_ptr_to_int32 char* string nscrt::hashcode() prunichar* string
nsastring hashstring() nsacstring nsid& nsidhashkey::hashkey() writing a good hash function is well beyond the scope of this document, and has been discussed extensively in computer-science circles for many years.
