inch, winch, mvinch, mvwinch - get a character
and attributes from a curses window
#include <curses.h>
chtype inch(void);
chtype winch(WINDOW *win);
chtype mvinch(int y, int x);
chtype mvwinch(WINDOW *win, int y, int x);
These routines return the character, of type chtype, at the
current position in the named window. If any attributes are set for that
position, their values are OR’ed into the value returned. Constants defined
in <curses.h> can be used with the & (logical AND) operator to extract the
character or attributes alone.
The following bit-masks may be
AND-ed with characters returned by winch.
| A_CHARTEXT | Bit-mask to extract character |
| A_ATTRIBUTES | Bit-mask
to extract attributes |
| A_COLOR | Bit-mask to extract color-pair field information |
Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window, or if
the window pointer is null.
Note that all of these routines may be
macros.
These functions are described in the XSI Curses standard,
Issue 4.
