Description

This lets you set up a plugin script function that will be called whenever a UDP packet arrives on the specified port.

This lets you set up a separate program which can communicate with MUSHclient by sending it UDP packets.

To listen to messages from any address use the address "0.0.0.0".

The address must be a dotted number, not a name (eg. "10.0.0.8")

You can cancel a listener by calling this function (for a previously-setup port) with an empty script name.

VBscript example

UdpListen "0.0.0.0", 4111, "MyScript"


Jscript example

UdpListen ("0.0.0.0", 4111, "MyScript")


Lua example

UdpListen ("0.0.0.0", 4111, "MyScript")


Return value

eNotAPlugin: This must be called from a plugin
eBadParameter: The port is already in use by another plugin, or the UDP socket could not be created
eNoNameSpecified: No script name was specified
eOK: succeeded
