.SH DESCRIPTION
|
|
The \fBwcsspn\fP() function is the wide-character equivalent of the
|
|
\fBstrspn\fP() function.
|
|
It determines the length of the longest initial segment of \fIwcs\fP
|
|
which consists entirely of wide-characters listed in \fIaccept\fP.
|
|
In other
|
|
words, it searches for the first occurrence in the wide-character string
|
|
\fIwcs\fP of a wide-character not contained in the wide-character string
|
|
\fIaccept\fP.
|
|
.SH "RETURN VALUE"
|
|
The \fBwcsspn\fP() function returns the number of
|
|
wide characters in the longest
|
|
initial segment of \fIwcs\fP which consists entirely of wide-characters listed
|
|
in \fIaccept\fP.
|
|
In other words, it returns the position of the first
|
|
occurrence in the wide-character string \fIwcs\fP of a wide-character not
|
|
contained in the wide-character string \fIaccept\fP, or \fIwcslen(wcs)\fP
|
|
if there is none.
