CRTL, mbsrtowcs, Description
*Conan The Librarian
This function converts a sequence of multibyte characters, beginning in the conversion state described by the object pointed to by ps, from the array indirectly pointed to by src, into a sequence of corresponding wide characters. If dst is not a NULL pointer, the converted characters are stored into the array pointed to by dst. Conversion continues up to and including a terminating null character, which is also stored. Conversion stops earlier for one of the following reasons: o A sequence of bytes is encountered that does not form a valid multibyte character. o If dst is not a NULL pointer, when len codes have been stored into the array pointed to by dst. If dst is not a NULL pointer, the pointer object pointed to by src is assigned either a NULL pointer, (if the conversion stopped because of reaching a terminating null wide character) or the address just beyond the last multibyte character converted (if any). If conversion stopped because of reaching a terminating null wide character, the resulting state described is the initial conversion state.
