curs_legacy(3X) curs_legacy(3X)
curs_legacy - get curses cursor and window coordinates,
attributes
#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);
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.
