NAME¶
wcscspn - search a wide-character string for any of a set of wide characters
SYNOPSIS¶
#include <wchar.h>
size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);
DESCRIPTION¶
The
wcscspn() function is the wide-character equivalent of the
strcspn(3) function. It determines the length of the longest initial
segment of
wcs which consists entirely of wide-characters not listed in
reject. In other words, it searches for the first occurrence in the
wide-character string
wcs of any of the characters in the
wide-character string
reject.
RETURN VALUE¶
The
wcscspn() function returns the number of wide characters in the
longest initial segment of
wcs which consists entirely of
wide-characters not listed in
reject. In other words, it returns the
position of the first occurrence in the wide-character string
wcs of
any of the characters in the wide-character string
reject, or
wcslen(wcs) if there is none.
ATTRIBUTES¶
Multithreading (see pthreads(7))¶
