.SH NAME
\fBin_wch\fR,
\fBmvin_wch\fR,
\fBmvwin_wch\fR,
\fBwin_wch\fR - extract a complex character and rendition from a window
.SH SYNOPSIS
\fB#include <curses.h>\fR
.sp
\fBint in_wch(cchar_t *\fR\fIwcval\fR\fB);\fR
.br
\fBint mvin_wch(int \fR\fIy\fR\fB, int \fR\fIx\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR
.br
\fBint mvwin_wch(WINDOW *\fR\fIwin\fR\fB, int \fR\fIy\fR\fB, int \fR\fIx\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR
.br
\fBint win_wch(WINDOW *\fR\fIwin\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR
.SH DESCRIPTION
These functions extract the complex character and rendition from
the current position in the named window into the \fBcchar_t\fR object
referenced by wcval.
.SH RETURN VALUE
No errors are defined in the XSI Curses standard.
This implementation checks for null pointers, returns ERR in that case.
Also, the \fImv\fR routines check for error moving the cursor, returning ERR
in that case.
Otherwise they return OK
.SH NOTES
Note that all of these routines may be macros.
.SH PORTABILITY
These functions are described in the XSI Curses standard, Issue 4.
.SH SEE ALSO

\fBcurs_inch\fR(3).
