NAME         top

       curs_legacy - get curses cursor and window coordinates,

SYNOPSIS         top

       #include <curses.h>

       int getattrs(const WINDOW *win);

       int getbegx(const WINDOW *win);
       int getbegy(const WINDOW *win);

       int getcurx(const WINDOW *win);
       int getcury(const WINDOW *win);

       int getmaxx(const WINDOW *win);
       int getmaxy(const WINDOW *win);

       int getparx(const WINDOW *win);
       int getpary(const WINDOW *win);

DESCRIPTION         top

       These legacy functions are simpler to use than the X/Open Curses

       •   The getattrs function returns the same attribute data as

           However, getattrs returns an integer (actually a chtype),
           while wattr_get returns the current color pair in a separate
           parameter.  In the wide-character library configuration,
           color pairs may not fit into a chtype, so wattr_get is the
           only way to obtain the color information.

           Because getattrs returns the attributes in a single
           parameter, it would not be possible for an application to
           distinguish that from ERR (a -1).  If the window parameter is
           null, getattrs returns A_NORMAL (zero).

       •   The getbegy and getbegx functions return the same data as

       •   The getcury and getcurx functions return the same data as

       •   The getmaxy and getmaxx functions return the same data as

       •   The getpary and getparx functions return the same data as

RETURN VALUE         top

       Except as noted, these functions return an integer, or ERR if the
       window parameter is null.

NOTES         top

       All of these interfaces are provided as macros and functions.
       The macros are suppressed (and only the functions provided) when
       NCURSES_OPAQUE is defined.  The standard forms such as getyx must
       be implemented as macros, and (in this implementation) are
       defined in terms of the functions described here, to avoid
       reliance on internal details of the WINDOW structure.

PORTABILITY         top

       These functions were supported on Version 7, BSD or System V
       implementations.  None of those implementations checked the
       window parameter.

       The getattrs function and macro are defined to return a (signed)
       integer for compatibility with those implementations although an
       unsigned type would have been more appropriate.
