wcsxfrm -- transform a wide string under locale
Standard C Library (libc, -lc)
wcsxfrm(wchar_t * restrict dst, const wchar_t * restrict src, size_t n);
The wcsxfrm() function transforms a nul-terminated wide-character string
pointed to by src according to the current locale collation order then
copies the transformed string into dst. No more than n wide characters
are copied into dst, including the terminating nul character added. If n
is set to 0 (it helps to determine an actual size needed for
transformation), dst is permitted to be a null pointer.
Comparing two strings using wcscmp() after wcsxfrm() is equivalent to
comparing two original strings with wcscoll().
Upon successful completion, wcsxfrm() returns the length of the
transformed string not including the terminating nul character. If this
value is n or more, the contents of dst are indeterminate.
setlocale(3), strxfrm(3), wcscmp(3), wcscoll(3)
The wcsxfrm() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
The current implementation of wcsxfrm() function disregards LC_COLLATE
locales, and falls back to using the wcsncpy() function.
