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.
For an explanation of the terms used in this section, see
attributes(7).
