ANSI_SYNOPSIS
|
||
|
|
#include <wchar.h>
|
||
|
|
int wcsxfrm(wchar_t *<[stra]>, const wchar_t * <[strb]>, size_t <[n]>);

TRAD_SYNOPSIS
|
||
|
|
#include <wchar.h>
|
||
|
|
size_t wcsxfrm(<[stra]>, <[strb]>, <[n]>)
|
||
|
|
wchar_t *<[stra]>;
|
||
|
|
wchar_t *<[strb]>;
|

|
|
size_t <[n]>

DESCRIPTION
|
||
|
|
<<wcsxfrm>> transforms the wide-character string pointed to by
|
||
|
|
<[strb]> to the wide-character string pointed to by <[stra]>,
|
||
|
|
Comparing two transformed wide strings with <<wcscmp>> should return
|
||
|
|
the same result as comparing the original strings with <<wcscoll>>.
|
||
|
|
No more than <[n]> wide characters are transformed, including the
|
||
|
|
trailing null character.
|
||
|
|
|
||
|
|
If <[n]> is 0, <[stra]> may be a NULL pointer.
|
||
|
|
|
||
|
|
The current implementation of <<wcsxfrm>> simply uses <<wcslcpy>>
|
||
|
|
and does not support any language-specific transformations.
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
<<wcsxfrm>> returns the length of the transformed wide character
|
||
|
|
string. if the return value is greater or equal to <[n]>, the
|
||
|
|
content of <[stra]> is undefined.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
<<wcsxfrm>> is ISO/IEC 9899/AMD1:1995 (ISO C).
