wctomb---minimal wide char to multibyte converter

Synopsis 
#include <stdlib.h>
int wctomb(char *s, wchar_t wchar);
Description
This is a minimal ANSI-conforming implementation of wctomb. The only "wide characters" recognized are single bytes, and they are "converted" to themselves.

Each call to wctomb copies the character wchar to *s, unless s is a null pointer.


Returns
This implementation of wctomb returns 0 if s is NULL; it returns 1 otherwise (reporting the length of the character "sequence" generated).


Portability
wctomb is required in the ANSI C standard. However, the precise effects vary with the locale.

wctomb requires no supporting OS subroutines.
