.SH DESCRIPTION
.sp
.LP
The \fBin_wchstr()\fR and \fBwin_wchstr()\fR functions retrieve a complex
character string (with rendition) starting at the current cursor position of
the \fBstdscr\fR window and window \fIwin\fR, respectively, and ending at  the
right margin. The \fBmvin_wchstr()\fR and \fBmvwin_wchstr()\fR functions
retrieve a complex character string located at the position indicated by the
\fIx\fR  (column) and \fIy\fR (row) parameters (the former in the \fBstdscr\fR
window; the latter in window \fIwin\fR).
.sp
.LP
The \fBin_wchnstr()\fR, \fBwin_wchnstr()\fR, \fBmvin_wchnstr()\fR, and
\fBmvwin_wchnstr()\fR functions retrieve at most \fIn\fR characters from the
window \fBstdscr\fR and \fIwin\fR, respectively. The former two functions
retrieve the string, starting at the current cursor  position; the latter two
commands retrieve the string, starting at the position  specified by the
\fIx\fR and \fIy\fR parameters.
.sp
.LP
The retrieved character string (with renditions) is stored in the object
pointed to by \fIwcval\fR.
