inch, winch, mvinch, mvwinch - get a character and
attributes from a curses window
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.
The following bit-masks may be AND-ed with characters
returned by winch.
l l . 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,
