+FUNCTION
+	<<wcscspn>>---get length of a complementary wide substring 
+
+ANSI_SYNOPSIS
+	#include <wchar.h>
+	size_t wcscspn(const wchar_t *<[s]>, wchar_t *<[set]>);
+
+TRAD_SYNOPSIS
+	size_t wcscspn(<[s]>, <[set]>
+	const wchar_t *<[s]>;
+	const wchar_t *<[set]>;
+
+DESCRIPTION
+	The <<wcscspn>> function computes the length of the maximum initial
+	segment of the wide-character string pointed to by <[s]> which consists
+	entirely of wide-character codes not from the wide-character string
+	pointed to by <[set]>. 
+
+RETURNS
+	The <<wcscspn>> function returns the length of the initial substring of
+	<[s1]>; no return value is reserved to indicate an error.
+
+PORTABILITY
+<<wcscspn>> is ISO/IEC 9899/AMD1:1995 (ISO C).
+
+No supporting OS subroutines are required.
