### 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
|
|
either y or x is -1, leaveok() is set TRUE, else it's set FALSE.
|
|
|
|
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.
