WCSCSPN(3) Linux Programmer's Manual WCSCSPN(3)

NAME

     wcscspn - search a wide-character string for any of a set of wide char-
     acters

SYNOPSIS

     #include <wchar.h>
     size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);

DESCRIPTION

     The wcscspn() function is the wide-character equivalent  of  the  strc-
     spn(3)  function.  It determines the length of the longest initial seg-
     ment of wcs which consists entirely of wide-characters  not  listed  in
     reject.   In  other  words, it searches for the first occurrence in the
     wide-character string wcs of any of the characters in the  wide-charac-
     ter string reject.

RETURN VALUE

     The  wcscspn()  function  returns  the number of wide characters in the
     longest initial segment of wcs which consists entirely of  wide-charac-
     ters  not listed in reject.  In other words, it returns the position of
     the first occurrence in the wide-character string wcs  of  any  of  the
     characters in the wide-character string reject, or wcslen(wcs) if there
     is none.
