VMS Help TCPIP Services, Programming Interfaces, RPC Server Routines, svctcp_create  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Creates an ONC RPC server handle for a TCP/IP connection.
    Format
      #include  <rpc/rpc.h>
      SVCXPRT  *svctcp_create(int sock, u_int sendsize, u_int
               recvsize);

1 - Arguments

 sock
    The socket with which the connection is associated. If sock is
    RPC_ANYSOCK, then this routine opens a new socket and sets sock.
    If the socket is not bound to a local TCP port, then this routine
    binds it to an arbitrary port.
 sendsize
    The size of the send buffer. If you specify 0, the routine
    chooses a suitable default.
 recvsize
    The size of the receive buffer. If you specify 0, the routine
    chooses a suitable default.

2 - Description

    Creates an RPC server handle using the TCP/IP transport, to
    which it returns a pointer. Upon completion, xprt->xp_sock is
    the transport's socket descriptor, and xprt->xp_port is the
    transport's port number. The service is automatically registered
    as a transporter (thereby including its socket in svc_fds such
    that its socket descriptor is included in all RPC select system
    calls).

3 - Return Values

    SVCXPRT *          A pointer to the server handle.
    NULL               Indicates failure.
