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.
Возвращаемое значение (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. 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.
