WCSXFRM(3)                 Library Functions Manual                 WCSXFRM(3)

NAME
     wcsxfrm -- transform a wide string under locale

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <&lt;wchar.h>&gt;

     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.
