In this model, client tasks request services of server tasks, and then wait for their reply. RPC formalizes this model and provides a standard protocol for passing requests and returning replies. Thus, a VxWorks or host system client task can request services from VxWorks or the host servers in any combination.</p><dd><p class="Body"><a name="89989"> </a>Internally, RPC uses sockets as the underlying communication mechanism. RPC, in turn, is used in the implementation of several higher-level facilities, including the Network File System (NFS) and remote source-level debugging. Also, RPC includes utilities to help generate the client interface routines and the server skeleton.</p><dd><p class="Body"><a name="89990"> </a>The VxWorks implementation of RPC is task-specific. Each task must call <b class="routine"><i class="routine">rpcTaskInit</i></b><b>(</b> <b>)</b> before making any RPC-related calls.</p><dd><p class="Body"><a name="89992"> </a>The VxWorks implementation of RPC was originally designed by Sun Microsystems and is in the public domain.
