curs_move.3x man page
move, wmove — move curses window cursor
int move(int y, int x);
int wmove(WINDOW *win, int y, int x);
These routines move the cursor associated with the window to line y and column x. This routine does not move the physical cursor of the terminal until refresh(3X) is called. The position specified is relative to the upper left-hand corner of the window, which is (0,0).
These routines return ERR upon failure and OK (SVr4 specifies only "an integer value other than ERR") upon successful completion.
Specifically, they return an error if the window pointer is null, or if the position is outside the window.
Note that move may be a macro.
These functions are described in the XSI Curses standard, Issue 4.
The man pages move.3x(3) and wmove.3x(3) are aliases of curs_move.3x(3).
