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

    Sends an error code to the client indicating that the requested
    program is registered with the Portmapper but the requested
    version of the program is not registered.
    Format
      #include  <rpc/rpc.h>
      void  svcerr_progvers(SVCXPRT *xprt, u_long low_vers, u_long
            high_vers);

1 - Arguments

 xprt
    A pointer to an RPC server handle created by any of the server
    handle creation routines.
 low_vers
    The lowest version of the requested program that the server
    supports.
 high_vers
    The highest version of the requested program that the server
    supports.

2 - Description

    Called when the desired version of a program is not registered
    with the ONC RPC package. Generally, the Portmapper informs
    the client when a requested program version is not registered.
    Therefore, service implementors usually do not use this routine.

3 - Return Values

    None
