It returns the number of wide-characters in the string pointed to by +\fIs\fP, not including the terminating L'\\0' character, but at most +\fImaxlen\fP. In doing this, \fBwcsnlen\fP looks only at the first \fImaxlen\fP +wide-characters at \fIs\fP and never beyond \fIs+maxlen\fP. +.SH "RETURN VALUE" +The \fBwcsnlen\fP function returns \fIwcslen(s)\fP, if that is less than +\fImaxlen\fP, or \fImaxlen\fP if there is no L'\\0' character among the +first \fImaxlen\fP wide characters pointed to by \fIs\fP. +.SH "CONFORMING TO" +This function is a GNU extension. +.SH "SEE ALSO" +.BR strnlen (3), +.BR wcslen (3) |
