NAME¶
inch,
winch,
mvinch,
mvwinch - get a character and
attributes from a
curses window
SYNOPSIS¶
#include <curses.h>
chtype inch(void);
chtype winch(WINDOW *win);
chtype mvinch(int y, int x);
chtype mvwinch(WINDOW *win, int y, int x);
DESCRIPTION¶
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 |
RETURN VALUE¶
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.
NOTES¶
Note that all of these routines may be macros.
PORTABILITY¶
These functions are described in the XSI Curses standard, Issue 4.
