inch, winch, mvinch, mvwinch - get a character and attributes from a
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 posi-
tion, 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
A_CHARTEXT Bit-mask to extract character
A_ATTRIBUTES Bit-mask to extract attributes
A_COLOR Bit-mask to extract color-pair field information
Note that all of these routines may be macros.
These functions are described in the XSI Curses standard, Issue 4.
