FUNCTION
|
|
<<wctomb>>---minimal wide char to multibyte converter
|
|
|
|
INDEX
|
|
wctomb
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <stdlib.h>
|
|
int wctomb(char *<[s]>, wchar_t <[wchar]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdlib.h>
|
|
int wctomb(<[s]>, <[wchar]>)
|
|
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.
