21 /* LOCATION */
22 struct IntuitionBase *, IntuitionBase, 89, Intuition)
24 /* FUNCTION
25 Gets the next public screen in the system; this allows visitor windows
26 to jump among public screens in a cycle.
28 INPUTS
29 screen - Pointer to the public screen your window is open in or
30 NULL if you don't have a pointer to a public screen.
31 namebuff - Pointer to a buffer with (at least) MAXPUBSCREENNAME+1
32 characters to put the name of the next public screen in.
34 RESULT
35 Returns 'namebuff' or NULL if there are no public screens.
37 NOTES
38 We cannot guarantee that the public screen, the name of which you got
39 by using this function, is available when you call for instance
40 LockPubScreen(). Therefore you must be prepared to handle failure of
41 that kind of functions.
43 This function may return the name of a public screen which is in
44 private mode.
46 The cycle order is undefined, so draw no conclusions based on it!
