FUNCTION
	<<wcsxfrm>>---locale-specific wide-character string transformation
 
INDEX
	wcsxfrm
 
ANSI_SYNOPSIS
	#include <wchar.h>
	int wcsxfrm(wchar_t *<[stra]>, const wchar_t * <[strb]>, size_t <[n]>);
 
TRAD_SYNOPSIS
	#include <wchar.h>
	size_t wcsxfrm(<[stra]>, <[strb]>, <[n]>)
	wchar_t *<[stra]>;
	wchar_t *<[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).
