+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).
