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

    The clnt_pcreateerror routine prints a message to SYS$OUTPUT. The
    message consists of the sp parameter followed by an RPC-generated
    error message. Use this routine when the clnt_create, clnttcp_
    create, or clntudp_create routine fails.
