SYNOPSISpdreceive port-number [udp|tcp]
DESCRIPTIONPdreceive opens a socket (with the specified port number) and waits for messages to arrive from one or more instances of pd(1). Each message received is printed to the standard output with a trailing semicolon. The protocol used is easy to implement and is called FUDI.
The port number should agree with the port number of a "netsend" object within pd. The protocol is "tcp" by default; this does a handshake to guarantee that all messages arrive complete and in their correct order; if you are sending messages locally or point-to-point you can often get away with the faster udp protocol instead.
You can also use this to get messages from a Max "pdnetsend" object or even just a "pdsend" in another shell. If you're writing another program you're welcome to just grab the sources for pdsend/pdreceive and adapt them to your own ends; they're part of the Pd distribution.
