NAME
1.38 `wctomb'--minimal wide char to multibyte converter
SYNOPSIS
#include <stdlib.h>
int wctomb(char *S, wchar_t WCHAR);
DESCRIPTION
When _MB_CAPABLE is not defined, this is a minimal ANSI-conforming
implementation of `wctomb'. The only "wide characters" recognized are
single bytes, and they are "converted" to themselves.
When _MB_CAPABLE is defined, this routine calls `_wctomb_r' to
perform the conversion, passing a state variable to allow state
dependent decoding. The result is based on the locale setting which may
be restricted to a defined set of locales.
Each call to `wctomb' modifies `*S' unless S is a null pointer or
_MB_CAPABLE is defined and WCHAR is invalid.
RETURNS
This implementation of `wctomb' returns `0' if S is `NULL'; it returns
`-1' if _MB_CAPABLE is enabled and the wchar is not a valid multi-byte
character, it returns `1' if _MB_CAPABLE is not defined or the wchar is
in reality a single byte character, otherwise it returns the number of
bytes in the multi-byte character.
PORTABILITY
`wctomb' is required in the ANSI C standard. However, the precise
effects vary with the locale.
`wctomb' requires no supporting OS subroutines.
