Description

This sends a single UDP (User Datagram Protocol) packet over the network, to the specified IP address and port.

The intention here is to communicate with other programs, such as the status-bar stand-alone program using UDP to send short messages.

You can broadcast to more than one PC by using a broadcast address.

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

VBscript example

UdpSend "10.0.0.3", 4111, "magic,textcolour,5555"


Jscript example

UdpSend ("10.0.0.3", 4111, "magic,textcolour,5555")


Lua example

UdpSend ("10.0.0.3", 4111, "magic,textcolour,5555")


Return value

If the packet was sent successfully, zero is returned. 

If the address could not be decoded, -1 is returned;
