| Curses Library Functions | curs_inch(3CURSES) |
| | curs_inch, inch, winch, mvinch, mvwinch - get a character and its attributes from a curses window |
SYNOPSIS
| |
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.
Attributes

- A_CHARTEXT
- Bit-mask to extract character
- A_ATTRIBUTES
- Bit-mask to extract attributes
