wcsxfrm
—locale-specific wide-character string transformation#include <wchar.h> int wcsxfrm(wchar_t *__restrict stra, const wchar_t *__restrict 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).
