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.
