implement wprintf family of functions this implementation is extremely ugly and inefficient, but it avoids a good deal of code duplication and bloat. it may be cleaned up later to eliminate the remaining code duplication and some of the warts, but i don't really care about its performance. note that swprintf is not yet implemented. 2011-03-17 22:55:43 -04:00			`#include <stdio.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			`int fwprintf(FILE restrict f, const wchar_t restrict fmt, ...)`
