|
|
*
|
|
* Description:
|
|
* The getyx() macro (defined in curses.h -- the prototypes here
|
|
* are merely illustrative) puts the current cursor position of the
|
|
* specified window into y and x. getbegyx() and getmaxyx() return
|
|
* the starting coordinates and size of the specified window,
|
|
* respectively. getparyx() returns the starting coordinates of the
|
|
* parent's window, if the specified window is a subwindow;
|
|
* otherwise it sets y and x to -1. These are all macros.
|
|
*
|
|
* getsyx() gets the coordinates of the virtual screen cursor, and
|
|
* stores them in y and x. If leaveok() is true, it returns -1, -1.
|
|
* If lines have been removed with ripoffline(), then getsyx()
|
|
* includes these lines in its count; so, the returned y and x
|
|
* values should only be used with setsyx().
|
|
*
|
|
* setsyx() sets the virtual screen cursor to the y, x coordinates.
|
|
* If y, x are -1, -1, leaveok() is set true.
|
|
*
|
|
* getsyx() and setsyx() are meant to be used by a library routine
|
|
* that manipulates curses windows without altering the position of
|
|
* the cursor. Note that getsyx() is defined only as a macro.
|
|
*
|
|
* getbegy(), getbegx(), getcurx(), getcury(), getmaxy(),
|
|
* getmaxx(), getpary(), and getparx() return the appropriate
|
|
* coordinate or size values, or ERR in the case of a NULL window.
