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			`size_t mbstowcs(wchar_t restrict ws, const char restrict s, size_t wn)`

minor optimization to mbstowcs there is no need to zero-fill an mbstate_t object in the caller; mbsrtowcs will automatically treat a null pointer as the initial state. 2013-04-04 14:51:05 -04:00			`return mbsrtowcs(ws, (void*)&s, wn, 0);`
