35 \fBwin_wch\fR \- extract a complex character and rendition from a window
37 \fB#include <curses.h>\fR
39 \fBint in_wch(cchar_t *\fR\fIwcval\fR\fB);\fR
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
45 \fBint win_wch(WINDOW *\fR\fIwin\fR\fB, cchar_t *\fR\fIwcval\fR\fB);\fR
47 These functions extract the complex character and rendition from
48 the current position in the named window into the \fBcchar_t\fR object
51 No errors are defined in the XSI Curses standard.
52 This implementation checks for null pointers, returns ERR in that case.
53 Also, the \fImv\fR routines check for error moving the cursor, returning ERR
55 Otherwise they return OK
57 Functions with a "mv" prefix first perform a cursor movement using
58 \fBwmove\fP, and return an error if the position is outside the window,
59 or if the window pointer is null.
61 Note that all of these routines may be macros.
63 These functions are described in the XSI Curses standard, Issue 4.
