wcsspn()
function is the wide-character equivalent of the
strspn(3)
function.
It determines the length of the longest initial segment of wcs
which consists entirely of wide-characters listed in accept.
#include <other>
words, it searches for the first occurrence in the wide-character string
wcs of a wide-character not contained in the wide-character string
accept.
RETURN VALUE
The
wcsspn()
function returns the number of
wide characters in the longest
initial segment of wcs which consists entirely of wide-characters listed
in accept.

occurrence in the wide-character string wcs of a wide-character not
contained in the wide-character string accept, or wcslen(wcs)
if there is none.
