curs_inch(3x)                                                    curs_inch(3x)




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 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.


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.
