wcsspn — advance in a wide-character string, skipping any of a set of wide characters
#include <wchar.h>

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).
