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

    Returns the local host's internet address according to a
    destination address.
    Format
      #include  <rpc/rpc.h>
      void  get_myaddr_dest(struct sockaddr_in *addr, struct
            sockaddr_in *dest);

1 - Arguments

 addr
    A pointer to a sockaddr_in structure that the routine will load
    with the local internet address which would provide a connection
    to the remote address specified in dest.
 dest
    A pointer to a sockaddr_in structure containing an internet
    address of a remote host.

2 - Description

    Since the local host may have multiple network addresses (each
    on its own interface), this routine is used to select the local
    address which would provide a connection to the remote address
    specified in dest.

    This is an alternative to gethostbyname, which invokes yellow
    pages. It takes a destination (where we are trying to get to) and
    finds an exact network match to go to.

3 - Return Values

    None
