hi all.. I've got a question regarding the zero-copy stuff.. I've currently got a handful of threads that have messages that are not allocated per-se (or may be taken from an STL vector behind the scenes). These messages are to be logged by a logging thread. Currently the code (which does work by the way), takes these messages to be logged (which are rather large), allocates a packet buffer with some housekeeping info and copies the passed-in data into the allocated packet area prior to calling zmqsend to the logging thread. I ran across, again, the paragraph in the guide talking about zero-copy and want to know if I omit the malloc/memcpy stuff if I'm going to get into trouble since the buffer may not be actually send (but would be queued) prior to the message buffer disappearing for whatever reason AFTER the zmq send returned and further processing performed by the thread that just finished logging that message.. Does that seem reasonable? I just want to make sure I'm not allocating/copying if I don't have to.. Thanks!
