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  move-
       ment  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.

       Comparable  functions  in  the  wide-character  (ncursesw)
       library are described in curs_in_wch(3x).
