NAME

       wcsspn, wcscspn - Return the length of the initial segment of a wide-character string

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <wchar.h>

       size_t wcsspn(	   const wchar_t *wcstring1,	  const wchar_t *wcstring2);

       size_t wcscspn(	    const wchar_t *wcstring1,	   const wchar_t *wcstring2);

PARAMETERS

       Points to a wide-character string being checked for an initial segment.	Points to a wide-character string containing a set of wide charac-
       ters that define the initial segment.

DESCRIPTION

       The wcsspn() and wcscspn() functions compute the number of wide characters in the initial segment of a wide-character string.  The wcsspn()
       function  considers the initial segment to consist of all wide characters that are included in the set of wide characters pointed to by the
       wcstring2 parameter. The function counts these wide characters until it finds one that is not included in the set.  The wcscspn()  function
       considers  the  initial	segment  to  consist  of all wide characters that are not included in the set of wide characters pointed to by the
       wcstring2 parameter. The function counts these wide characters until it finds one that is included in the set.

RETURN VALUES

       On successful completion, the wcsspn() and wcscspn() functions return the number of wide characters in the segment.   No  error	return	is
       defined for these functions.
