curs_in_wch(3) Library calls curs_in_wch(3)
NAME
in_wch, mvin_wch, mvwin_wch, win_wch - get a curses complex character
from a window
SYNOPSIS
#include <curses.h>
int in_wch(cchar_t *wch);
int win_wch(WINDOW *win, cchar_t *wch);
int mvin_wch(int y, int x, cchar_t *wch);
int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wch);
DESCRIPTION
These functions extract the complex character and rendition from the
current position in the named window into the cchar_t object referenced
by wch.
RETURN VALUE
No errors are defined in X/Open Curses. This implementation checks for
null pointers, returns ERR in that case. Also, the mv routines check
for error moving the cursor, returning ERR in that case. Otherwise
they return OK.
Functions prefixed with "mv" first perform cursor movement and fail if
the position (y, x) is outside the window boundaries.
NOTES
Note that all of these routines may be macros.
PORTABILITY
These functions are described in X/Open Curses, Issue 4.
