Name
       rpc_use_family_wk - create a socket with a well-known port for a remote procedure call (RPC) server (server only)

Syntax
       #include <idl/c/rpc.h>

       void rpc_$use_family_wk(family, ifspec, sockaddr, slength, status)
       unsigned long family;
       rpc_$if_spec_t *ifspec;
       socket_$addr_t *sockaddr;
       unsigned long *slength;
       status_$t *status;

Arguments
       family	      The  address  family  of the socket to be created.  This value corresponds to the communications protocol used to access the
		      socket and determines how the sockaddr is expressed.  The value must be one of socket_$unspec or socket_$internet.

       ifspec	      The interface that will be registered by the server.  Typically, this parameter is the interface if_spec	generated  by  the
		      NIDL compiler from the interface definition; the well-known port is specified as an interface attribute.

       sockaddr       The socket address of the socket on which the server will listen.

       slength	      The length, in bytes, of sockaddr.

       status	      The  completion status.  If the completion status returned in is equal to status_$ok , then the routine that supplied it was
		      successful.

Description
       The routine creates a socket that uses the port specified through the if_spec parameter.  Use this routine to create a  socket  only  if  a
       server must listen on a particular well-known port.  Otherwise, use

       A  server  listens  on one socket per address family, regardless of how many interfaces that it exports.  Therefore, servers that use well-
       known ports should make this call once per supported address family.

Examples
       The following statement creates the well-known socket identified by for an array processor server:
       rpc_$use_family_wk (socket_$internet, &matrix$if_spec,
			      &sockaddr, &slen, &status);

Diagnostics
       This section lists status codes for errors returned by this routine in

       rpc_$cant_create_sock
			   The RPC runtime library was unable to create a socket.

       rpc_$not_in_call    An internal error.

       rpc_$proto_error    An internal protocol error.

       rpc_$too_many_sockets
			   The server is trying to use more than the maximum number of sockets that is allowed; it has called or too many times.

       rpc_$bad_pkt	   The server or client has received an ill-formed packet.

       rpc_$addr_in_use    The address and port specified in an routine are already in use.  This is caused by multiple calls  to  with  the  same
			   well-known port.
