.SH DESCRIPTION
.sp
.LP
If \fIwch\fR is not a null pointer, the \fBgetcchar()\fR function splits the  \fBcchar_t\fR object pointed to by \fIwcval\fR into a wide character string, attributes, and a color pair. It stores the attributes in the location pointed to by \fIattrs\fR, the color  pair in the location pointed to by \fIcolor_pair\fR, and the wide character string in the location pointed to by \fIwch\fR.
.sp
.LP
If \fIwch\fR is a null pointer, the \fBgetcchar()\fR function simply returns  the number of wide characters in the \fBcchar_t\fR object pointed to by  \fIwcval\fR. The objects pointed to by \fIattrs\fR and \fIcolor_pair\fR are not changed.
