UDPUNBIND Keyword

UDPUNBIND string-expression, port

Stops receiving UDP datagrams on a previously bound port. Any queued packets for that port are no longer delivered.

• string-expression is the local IP address used at bind time (currently ignored).
• port must be in the range 0 to 65535.

Note

If port is outside the valid range, an error is raised: Invalid UDP port number.

How to read it

• Use UDPUNBIND to stop delivery when you no longer want to read from the port.

Notes

• Unbinding while packets are still queued discards them from further reads.
