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.
