The use case is multithreading, as done in CZMQ. Child threads can be "attached" to the main thread via a pipe, automatically created and destroyed. These pipes are perfect for ZMQ_PAIR, since CZMQ is in full control of the create/bind/connect flow. Using ZMQ_PAIR assures that the pipes cannot be misused by accident or maliciously. We _could_ drop PAIR quite trivially by using DEALER instead, if there was a socket option to restrict the number of connecting peers (to 1 to emulate PAIR). But the PAIR semantics are clear and useful IMO. -Pieter _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
