add all missing wchar functions except floating point parsers these are mostly untested and adapted directly from corresponding byte string functions and similar. 2012-03-01 23:24:45 -05:00			`#include <wchar.h>`

use restrict everywhere it's required by c99 and/or posix 2008 to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict. 2012-09-06 22:44:55 -04:00			`wchar_t wcstok(wchar_t restrict s, const wchar_t restrict sep, wchar_t *restrict p)`
