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
.
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.
