That should be how it's used, yes. The parameter is optional, so if you don't submit a method/function there, you will have to take care of deleting yourself.

April 2011 15:53 To: ZeroMQ Mailing list Subject: [zeromq-dev] Newbie questions Hello list, I'm a complete newbie in the use and application of Zeromq so I am sure my questions will sound quite inane and downright stupid. I apologise in advance. I stumbled on ZeroMQ early this week while googling for a decent message system that is'nt implemented in Java. I use FPC(FreePascal) and Lazarus (both Open Source products) as my programming platform and intend to write a binding as well as component/s to enable the use of ZeroMQ with FPC. Unfortunately, I am not very C proficient, so I am also doing a crash course in C/C++ at the moment. I have already started the port and I'm ironing out the wrinkles in my interface unit .....So much for the intro, here's my question: >From the api documentation on the web it seems that the variable ffn of type >zmq_free_fn as defined in the parameters of zmq_msg_init_data is a user >supplied function and one needs to pass a pointer to a function that will free >the message data. Is this correct? Regards
