wcsxfrm3
Transform a wide string under locale
Usage
#include <wchar.h>
size_t
wcsxfrm(wchar_t *restrict ws1, const wchar_t *restrict ws2, size_t n);
#include <wchar.h>
#include <xlocale.h>
size_t
wcsxfrm_l(wchar_t *restrict ws1, const wchar_t *restrict ws2, size_t n, locale_t loc);
Library
Standard C Library (libc, -lc)
Overview
The wcsxfrm() function transforms a null-terminated wide character string pointed to by ws2, according to the current locale's collation order, then copies the transformed string into ws1. No more than n wide characters are copied into ws1, including the terminating null character. If n is set to 0 (it helps to determine an actual size needed for transformation), ws1 is permitted to be a NULL pointer.
Comparing two strings using wcscmp() after wcsxfrm() is equivalent to comparing two original strings with wcscoll().
Although the wcsxfrm() function uses the current locale, the wcsxfrm_l() function may be passed a locale directly. See xlocale(3) for more information.
Return values
Upon successful completion, wcsxfrm() returns the length of the transformed string not including the terminating null character. If this value is n or more, the contents of ws1 are indeterminate.
