NAME
     mmbbssttoowwccss, mmbbssttoowwccssll - convert a character string to a wide-character
     string

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>

     sizet
     mmbbssttoowwccss(wchart * restrict wcstring, const char * restrict mbstring,
         sizet nwchars);

     ##iinncclluuddee <>

     sizet
     mmbbssttoowwccssll(wchart * restrict wcstring, const char * restrict mbstring,
         sizet nwchars, localet loc);

DESCRIPTION
     The mmbbssttoowwccss() function converts a multibyte character string mbstring
     beginning in the initial conversion state into a wide character string
     wcstring.  No more than nwchars wide characters are stored.  A terminat-
     ing null wide character is appended if there is room.

     While the mmbbssttoowwccss() function uses the current locale, the mmbbssttoowwccssll()
     function may be passed a locale directly. See xlocale(3) for more infor-
     mation.

RETURN VALUES
     The mmbbssttoowwccss() function returns the number of wide characters converted,
     not counting any terminating null wide character, or -1 if an invalid
     multibyte character was encountered.

EERRRROORRSS
     The mmbbssttoowwccss() function will fail if:

     [EILSEQ]           An invalid multibyte sequence was detected.

     [EINVAL]           The conversion state is invalid.
