wctomb - Convert wide character to multibyte character

Definition	#include <stdlib.h> int wctomb(char *s, wchar_t wc); wctomb converts the wide character wc to the corresponding multibyte character and stores this in string s. No assignment is made if s is a NULL pointer or if the wide character cannot be represented in one byte.
Return val.	0	if s is a NULL pointer.
	-1	if the wide character cannot be converted to a multibyte character.
	1	otherwise.
Note	This version of the C runtime system only supports one-byte characters as wide character codes. Multibyte characters and wide character codes always have a length of 1 byte.
