getmaxy3x
Get curses cursor and window coordinates or attributes (legacy)
Part of curs_legacy(3x).
Usage
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);
Overview
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.
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.
