DESCRIPTION

     These functions and macros locate and position cursors and windows.

     The getcury() and getcurx() functions get the current row and column
     positions, respectively, of the cursor in the window win.  The getyx()
     macro sets the values of y and x to the current row and column positions
     of the cursor in the window win.

     The getsyx() macro sets the values of y and x of the current window if
     is_leaveok() is false, otherwise -1, -1.  The setsyx() macro sets the row
     and column positions, respectively, of the cursor in the current window
     to the values of y and x.  If both y and x are both -1 then leaveok() is
     set.

     The origin row and columns of a window win can be determined by calling
     the getbegy() and getbegx() functions, respectively, and the maximum row
     and column for the window can be found by calling the functions getmaxy()
     and getmaxx(), respectively.  The getbegyx() and getmaxyx() macros set
     the values of y and x to the origin and maximum row and column positions,
     respectively, for the window win.

     The getpary() and getparx() functions return the row and column position
     of the given subwindow relative to the window's parent.  The macro
     getparyx() sets the values of y and x to the origin of the subwindow rel-
     ative to the window's parent.

     The move() function positions the cursor on the current window at the
     position given by y, x.  The cursor position is not changed on the screen
     until the next refresh().

     The wmove() function is the same as the move() function, excepting that
     the cursor is moved in the window specified by win.

     The function mvcur() moves the cursor to y, x on the screen.  The argu-
     ments oldy, oldx define the previous cursor position for terminals that
     do not support absolute cursor motions.  The curses library may optimise
     the cursor motion based on these values.  If the mvcur() succeeds then
     the curses internal structures are updated with the new position of the
     cursor.  If the destination arguments for mvcur() exceed the terminal
     bounds an error will be returned and the cursor position will be
     unchanged.

     The wcursyncup() function sets the cursor positions of all ancestors of
     win to that of win.


RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification,
     part of the Single Unix Specification.  The getbegx(), getbegy(),
     getcurx(), getcury(), getmaxx(), getmaxy(), getparx(), and getpary()
     functions are extensions.


HISTORY

     The Curses package appeared in 4.0BSD.  The getsyx() and setsyx() func-
     tions are ncurses extensions to the Curses library and were added in
     NetBSD 8.0.
