wcsspn - advance in a wide-character string, skipping any of a set of wide
characters
#include <wchar.h>
size_t wcsspn(const wchar_t *wcs, const wchar_t *accept);
The 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. In 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.
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. In other words, it returns the position of the first 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.
