46 * Get the current screen coordinates (y, x).
47 *
48 * The current screen coordinates are defined as the last place that
49 * the cursor was placed by a wnoutrefresh(), pnoutrefresh() or setsyx()
50 * call. If leaveok() was true for the last window refreshed, then
51 * return (-1, -1) so that setsyx() can reset the leaveok flag.
52 *
53 * This function is actually called by the macro getsyx(y, x), which is
54 * defined in curses.h as:
55 *
56 * #define getsyx(y, x) _getsyx(&y, &x)
57 *
58 * Note that this macro just adds in the '&'. In this way, getsyx()
59 * is parallel with the other getyx() routines which don't require
60 * ampersands. The reason that this can't all be a macro is that
61 * that we need to access SP, which is normally not available in
62 * user-level routines.
