+FUNCTION
+	<<wcsncat>>---concatenate part of two wide-character strings 
+
+ANSI_SYNOPSIS
+	#include <wchar.h>
+	wchar_t *wcsncat(wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>);
+
+TRAD_SYNOPSIS
+	wchar_t *wcsncat(<[s1]>, <[s2]>, <[n]>
+	wchar_t *<[s1]>;
+	const wchar_t *<[s2]>;
+	size_t <[n]>;
+
+DESCRIPTION
+	The <<wcsncat>> function appends not more than <[n]> wide-character
+	codes (a null wide-character code and wide-character codes that follow
+	it are not appended) from the array pointed to by <[s2]> to the end of
+	the wide-character string pointed to by <[s1]>. The initial
+	wide-character code of <[s2]> overwrites the null wide-character code
+	at the end of <[s1]>.
+	A terminating null wide-character code is always appended to the result.
+	If copying takes place between objects that overlap, the behaviour is
+	undefined.
+
+RETURNS
+	The <<wcsncat>> function returns <[s1]>; no return value is reserved to
+	indicate an error.
+
+PORTABILITY
+<<wcsncat>> is ISO/IEC 9899/AMD1:1995 (ISO C).
+No supporting OS subroutines are required.
