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.
