SYNOPSIS

     #include <stdlib.h>

     size_t
     wcstombs(char * restrict mbstring, const wchar_t * restrict wcstring,
	 size_t nbytes);

DESCRIPTION

     The wcstombs() function converts a wide character string wcstring into a

     acter string is null terminated if there is room.

RETURN VALUES

     The wcstombs() function returns the number of bytes converted (not
     including any terminating null), if successful, otherwise it returns
     (size_t)-1.

ERRORS

     The wcstombs() function will fail if:

     [EILSEQ]		An invalid wide character was encountered.

     [EINVAL]		The conversion state is invalid.
