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-character 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-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.
ATTRIBUTES¶
