  NAME

    svc_getreqset, svc_getreq - Library functions for remote procedure calls

  LIBRARY

    Berkeley Software Distribution Library (libbsd.a)

  SYNOPSIS

    void svc_getreqset(
      fd_set *rdfds );

    void svc_getreq(
      int rdfds );

  PARAMETERS

    rdfds   Points to the mask of file descriptors with data available,
            returned by select().

  DESCRIPTION

    The svc_getreqset() and svc_getreq() functions allow C programs to make
    procedure calls on other machines across the network.  First, the client
    calls a procedure to send a data packet to the server.  Upon receipt of
    the packet, the server calls a dispatch routine to perform the requested
    service, and then sends back a reply.  Finally, the procedure call returns
    to the client.

    The svc_getreqset() function is only of interest if a service implementor
    does not call svc_run(), but instead implements custom asynchronous event
    processing.  The svc_getreqset() routine is called when the select()
    function has determined that an RPC request has arrived on some RPC
    sockets.  The rdfds parameter is the resultant read file descriptor bit
    mask.

    The svc_getreq() function is similar to svc_getreqset(), but limited to 32
    descriptors.  The svc_getreq() interface is obsoleted by svc_getreqset().

  RETURN VALUES

    The svc_getreqset() and svc_getreq() functions return void when all
    sockets associated with the value of rdfds have been serviced.
