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.
