.SH NAME
\fB\%in_wch\fP,
\fB\%mvin_wch\fP,
\fB\%mvwin_wch\fP,
\fB\%win_wch\fP \-
get a \fIcurses\fR complex character from a window
.SH SYNOPSIS
.nf
\fB#include <curses.h>
.PP
\fBint in_wch(cchar_t *\fIwch\fP);
\fBint win_wch(WINDOW *\fIwin\fP, cchar_t *\fIwch\fP);
.PP
\fBint mvin_wch(int \fIy\fP, int \fIx\fP, cchar_t *\fIwch\fP);
\fBint mvwin_wch(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, cchar_t *\fIwch\fP);
.fi
.SH DESCRIPTION
These functions extract the complex character and rendition from
the current position in the named window into the \fBcchar_t\fP object
referenced by wch.
.SH RETURN VALUE
No errors are defined in X/Open Curses.
This implementation checks for null pointers, returns \fBERR\fP in that case.
Also, the \fImv\fP routines check for error moving the cursor,
returning \fBERR\fP in that case.
Otherwise they return \fBOK\fP.
.PP
Functions prefixed with \*(``mv\*('' first perform cursor movement and
fail if the position
.RI ( y ,
.IR x )
is outside the window boundaries.
.SH NOTES
Note that all of these routines may be macros.
.SH PORTABILITY
These functions are described in X/Open Curses, Issue 4.
.SH SEE ALSO
\fB\%curs_inch\fP(3X) describes comparable functions of the
.I \%ncurses
library in its non-wide-character configuration.
