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
.
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.
