- The getbegy and getbegx functions return the same data as getbegyx.
+ These legacy functions are simpler to use than the X/Open Curses func-
+ tions:
- The getcury and getcurx functions return the same data as getyx.
+ o The getattrs function returns the same attribute data as wattr_get.
- The getmaxy and getmaxx functions return the same data as getmaxyx.
+ 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.
- The getpary and getparx functions return the same data as getparyx.
+ 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).
