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 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 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.
