mbsrtowcs -- convert a character string to a wide-character string
Standard C Library (libc, -lc)
mbsrtowcs(wchar_t * restrict dst, const char ** restrict src, size_t len,
mbstate_t * restrict ps);
The mbsrtowcs() function converts a sequence of multibyte characters
pointed to indirectly by src into a sequence of corresponding wide characters
and stores at most len of them in the wchar_t array pointed to by
dst, until it encounters a terminating null character ('\0').
If dst is NULL, no characters are stored.
If dst is not NULL, the pointer pointed to by src is updated to point to
the character after the one that conversion stopped at. If conversion
stops because a null character is encountered, *src is set to NULL.
The mbstate_t argument, ps, is used to keep track of the shift state. If
it is NULL, mbsrtowcs() uses an internal, static mbstate_t object.
The mbsrtowcs() function returns the number of wide characters stored in
the array pointed to by dst if successful, otherwise it returns
The mbsrtowcs() function will fail if:
[EILSEQ] An invalid multibyte character sequence was encountered.

The mbsrtowcs() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
The current implementation does not support shift states.
