It is a library that augments standard -networking sockets by special capabilities that you can otherwise get only -by using specialised "messaging middleware" products, such as automated -handling of connections and disconnections, delivery of a message to multiple -destinations, load balancing messages, sophisticated message filtering etc. - -0MQ is designed to be extremely fast. Expected end-to-end latencies for -messages passed over a LAN are in tens of microseconds. Expected -throughputs are to be measured in millions of messages per second. - -0MQ is designed to be very thin. It requires no more than couple of -pages in resident memory and is thus well suited for any environment ranging -from small embedded devices, routers and cell phones to enterprise-scale -data centers. - -0MQ runs on a wide range of operating systems and supports variety of processor -microarchitectures. - -0MQ is accessible from a large set of programming languages. - -0MQ is fully open sourced LGPL-licensed software. - -.SH CONTEXT -Each 0MQ socket lives within a specific context. Creating and destroying -context is a counterpart of library initialisation/deinitialisation as used -elsewhere.
