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.

SEE ALSO

       Comparable functions in the wide-character (ncursesw) library are described in in_wch(3NCURSES).
