NAME

       curs_legacy - get curses cursor and window coordinates, attributes

SYNOPSIS

       #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

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

       •   The getattrs function returns the same attribute data as wattr_get.

           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 getbegyx.

       •   The getcury and getcurx functions return the same data as getyx.

       •   The getmaxy and getmaxx functions return the same data as getmaxyx.

       •   The getpary and getparx functions return the same data as getparyx.

RETURN VALUE

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

NOTES

       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

       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.
