The Cascade NameServer (nserve) is a necessary part of a system using the IP_* functions. Its purpose is to map a node, a process ID, and (in QNX 6) a channel ID, to a process name. A program that uses the Cogent IP_* library functions will normally declare a name with nserve in order to advertise its presence. nserve also carries a queue name for asynchronous communication, and a Cascade DataHub domain name where applicable.
For more information on nserve see: The Cascade NameServer chapter of this manual.
