     getpary(WINDOW *win);

     int
     getparx(WINDOW *win);

     void
     getparyx(WINDOW *win, int y, int x);

     int
     move(int y, int x);

     int
     wmove(WINDOW *win, int y, int x);

     int

     void
     wcursyncup(WINDOW *win);

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 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 relative 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 arguments 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.
