| .SH SYNOPSIS |

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