Further information
1. This procedure sends a broadcast message over the local network and waits for replies from running
xprmsrv servers (see Section
The Mosel Remote Launcher xprmsrv). A given server will reply only to selected
group numbers: the
group argument specifies this property.
2. The IP addresses of the hosts having replied to the request are returned via the last argument of the procedure in the form of strings. The maximum size of this set is fixed by maxip. Note that the provided set is not cleared: if it already contains
maxip elements the routine returns immediately.
3. Control parameters
fsrvnbiter,
fsrvdelay and
fsrvport can be used to tune the behaviour of
findxsrvs. This routine repeats
fsrvnbiter times the following procedure: it sends a broadcast message to the
fsrvport UDP port and then waits for up to
fsrvdelay milliseconds for replies.
