Steve Kondikae271bc2015-11-15 02:50:53 +0100[diff] [blame]35\fBwin_wch\fR \- extract a complex character and rendition from a window
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530[diff] [blame]36.SH SYNOPSIS
37\fB#include <curses.h>\fR
38.sp
39\fBint in_wch(cchar_t *\fR\fIwcval\fR\fB);\fR
40.br
41\fBint mvin_wch(int \fR\fIy\fR\fB, int \fR\fIx\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR

43\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
44.br
45\fBint win_wch(WINDOW *\fR\fIwin\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR
46.SH DESCRIPTION
47These functions extract the complex character and rendition from
48the current position in the named window into the \fBcchar_t\fR object
49referenced by wcval.
50.SH RETURN VALUE
51No errors are defined in the XSI Curses standard.
52This implementation checks for null pointers, returns ERR in that case.
53Also, the \fImv\fR routines check for error moving the cursor, returning ERR
54in that case.
55Otherwise they return OK
Steve Kondikae271bc2015-11-15 02:50:53 +0100[diff] [blame]56.PP
57Functions with a "mv" prefix first perform a cursor movement using
58\fBwmove\fP, and return an error if the position is outside the window,
59or if the window pointer is null.
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530[diff] [blame]60.SH NOTES
61Note that all of these routines may be macros.
62.SH PORTABILITY
63These functions are described in the XSI Curses standard, Issue 4.
