getattrs, getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy,
getparx, getpary - get curses cursor and window coordinates or
attributes (legacy)
#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:
o 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).
o The getbegy and getbegx functions return the same data as getbegyx.
o The getcury and getcurx functions return the same data as getyx.
o The getmaxy and getmaxx functions return the same data as getmaxyx.
o 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.
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.
