wctomb - convert wide character code to character

Syntax	#include <stdlib.h> int wctomb(char *s, wchar_t wchar);
Description	wctomb() converts the wchar_t value wchar to the appropriate multi-byte character and stores it in string s. No characters consisting of multiple bytes are implemented in this version. Multi-byte characters always have a length of 1 byte, and wchar_t values are always of type long. wcstomb() assigns the wchar_t value (of type long) to the area s, of 1-byte length. No assignment occurs if s is a null pointer or if the wchar_t value cannot be represented in 1 byte.
Return val.	0	if s is a null pointer.
	-1	if the wchar_t value cannot be converted to a multi-byte character.
	1	in all other cases.
Notes	Restriction This version of the C runtime system only supports 1-byte characters as wide character codes. They are of type wchar_t (see stddef.h). (End)
