[13:45] Guthur I see someone mention compiled binary size on ARM cores on the mailing list...
[13:46] Guthur can ZeroMQ be successfully cross compiled for the ARM
[14:04] sustrik Guthur: iirc someone have done it
[14:04] sustrik there should be a mail about it on the mailing list
[14:05] sustrik or maybe a wiki page on the site
[14:05] Guthur sustrik, I'll have a look
[14:05] Guthur Is there some search mechanism for the mailing list bar google
[14:10] Guthur oh nvm
[14:32] Guthur pieterh, I have the opportunity of presenting ZeroMQ to my team at work, any suggestions on content
[16:17] Eruquen is there a difference between zmq_zmsg_t and zmsg_t?
[16:18] sustrik what's zmsg_t?
[16:21] Eruquen a type that is used in the C examples
[16:22] Eruquen maybe that's why I get abitrary results vom zmq_msg_size
[16:42] sustrik i assume it's some layer on top of 0mq that's used by the guide
[16:42] sustrik no idea how it works
[16:42] sustrik sorry
[16:52] Guthur Eruquen, source is here
[16:52] Guthur it provides some useful helper functions for msg
[18:30] Zevv Hi all. Just learned about 0mq, seems that this can fix a lot of my daily pains. One question: is it possible in a inproc environment to pass pointers around ? I'm considering if 0mq can be used in our app which shares video data among a few threads on an embedded device which is painfully slow doing memcpy()'s
[18:31] Zevv most of the messaging is probably ok to do using 0mq, but only the video data itself - several MB's per frame - can not be copied around for performance reasons
[18:31] Zevv is this a known scenario ?
[18:58] Guthur Zevv, sure you could pass the memory address around if you want
[19:17] sustrik dermoth|home: ZMQ_BACKLOG has to do only with connecting, it has no effect on messages themselves
[19:17] sustrik see man listen
[20:08] sustrik let me see
[20:09] sustrik yes, it can
[20:11] sustrik :)
[20:30] Guthur surely if it couldn't that would be a big issue
[22:43] thatch Is there a way to verify that a remote zeromq server is available before atempting to connect to it?
[23:05] Guthur thatch__, you could checkout chapter 4 of the guide for some reliability patterns
[23:05] thatch thanks :)
