curs_legacy - get curses cursor and window coordinates, attributes
#include <ncurses/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);
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.
Except as noted, these functions return an integer, or ERR if the window
parameter is null.
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.
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.
