RPC provides facilities for implementing distributedclient/server-based architectures. The underlying communication mechanismcan be completely hidden, permitting applications to be written withoutany reference to network sockets. The package is structured such thatlower-level routines can optionally be accessed, allowing greater controlof the communication protocols.<p>For more information and a tutorial on RPC, see Sun Microsystems'<i>Remote Procedure Call Programming Guide. </i>For an example of RPC usage, see <b>/target/unsupported/demo/sprites</b>.<p>The RPC facility is enabled when <b>INCLUDE_RPC</b> is defined.<p>VxWorks supports Network File System (NFS), which is builton top of RPC. If NFS is configured into the VxWorks system,RPC is automatically included as well.<p></blockquote><h4>IMPLEMENTATION</h4><blockquote><p>A task must call <b><a href="./rpcLib.html#rpcTaskInit">rpcTaskInit</a>( )</b> before making any calls to otherroutines in the RPC library. This routine creates task-specific datastructures required by RPC. These task-specific data structures areautomatically deleted when the task exits.<p>Because each task has its own RPC context, RPC-related objects (such asSVCXPRTs and CLIENTs) cannot be shared among tasks; objects created by onetask cannot be passed to another for use. Such additional objects mustbe explicitly deleted (for example, using task deletion hooks).<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>rpc.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./nfsLib.html#top">nfsLib</a></b>, <b><a href="./nfsDrv.html#top">nfsDrv</a></b>, Sun Microsystems'<i>Remote Procedure Call Programming Guide </i><hr><a name="rpcInit"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>rpcInit( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>rpcInit( )</strong> - initialize the RPC package</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS rpcInit (void)</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine must be called before any task can use the RPC facility; it spawns the portmap daemon.
