NetBSD 6.1.5 - man page for wcsxfrm (netbsd section 3)

WCSXFRM(3)			   BSD Library Functions Manual 		       WCSXFRM(3)

NAME
     wcsxfrm -- transform a wide string under locale

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wchar.h>

     size_t
     wcsxfrm(wchar_t * restrict dst, const wchar_t * restrict src, size_t n);

DESCRIPTION
     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().

RETURN VALUES
     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.

SEE ALSO
     setlocale(3), strxfrm(3), wcscmp(3), wcscoll(3)

STANDARDS
     The wcsxfrm() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

BUGS
     The current implementation of wcsxfrm() function disregards LC_COLLATE locales, and falls
     back to using the wcsncpy() function.
