WCSSPN(3) Linux Programmer's Manual WCSSPN(3)
NAME
wcsspn - advance in a wide-character string, skipping any of a set of wide characters
SYNOPSIS
#include <wchar.h>
size_t wcsspn(const wchar_t *wcs, const wchar_t *accept);
DESCRIPTION
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-char-
acter 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-charac-
ters listed in accept. In other words, it returns the position of the first occurrence in the wide-character string wcs of a wide-charac-
ter not contained in the wide-character string accept, or wcslen(wcs) if there is none.
