48 * Get the current screen coordinates (y, x).
49 *
50 * The current screen coordinates are defined as the last place that
51 * the cursor was placed by a wnoutrefresh(), pnoutrefresh() or setsyx()
52 * call. If leaveok() was true for the last window refreshed, then
53 * return (-1, -1) so that setsyx() can reset the leaveok flag.
54 *
55 * This function is actually called by the macro getsyx(y, x), which is
56 * defined in curses.h as:
57 *
58 * #define getsyx(y, x) _getsyx(&y, &x)
59 *
60 * Note that this macro just adds in the '&'. In this way, getsyx()
61 * is parallel with the other getyx() routines which don't require
62 * ampersands. The reason that this can't all be a macro is that
63 * that we need to access SP, which is normally not available in
64 * user-level routines.
