curs_inch, inch, winch, mvinch, mvwinch - get a character and its attributes from a curses window
cc [ flag ... ] file ... –lcurses [ library ... ] #include <curses.h> chtype inch(void);
chtype winch(WINDOW *win);
chtype mvinch(int y, int x);
chtype mvwinch(WINDOW *win, int y, int x);
With these routines, the character, of type chtype, at the current position in the named window is returned. 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 can be AND-ed with characters returned by winch().
Bit-mask to extract character
Bit-mask to extract attributes
Bit-mask to extract color-pair field information
See attributes(7) for descriptions of the following attributes:
The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.
Note that all of these routines may be macros.
