The value of \fIwc\fR must be a character representable as a \fBwchar_t\fR, and must be a wide-character code corresponding to a valid character in the current locale. .SH RETURN VALUES .sp .LP The \fBwcwidth()\fR function either returns \fB0\fR (if \fIwc\fR is a null wide-character code), or returns the number of column positions to be occupied by the wide-character code \fIwc\fR, or returns \fB\(mi1\fR (if \fIwc\fR does not correspond to a printing wide-character code). .SH ERRORS .sp .LP No errors are defined. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
