curs_inch(3X) curs_inch(3X)
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.
Attributes
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.
curses(3X).
Comparable functions in the wide-character (ncursesw) library are
described in curs_in_wch(3X).
