Responds to an incoming connection request. This call is used to
    complete an ICC connection from the server side.

    On Alpha and Integrity server systems, this service accepts 64-
    bit addresses.

1  –  Arguments

 conn_handle

    OpenVMS usage:connection_id
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The handle of the requested connection.

 accept_buf

    OpenVMS usage:byte_stream
    type:         character-coded text string
    access:       read only
    mechanism:    by 32-bit or 64-bit reference (Alpha and Integrity
                  servers)
    A buffer of up to 1000 bytes of accept data that is sent to the
    source of the connection at the completion of the connection
    process.

 accept_len

    OpenVMS usage:buffer_length
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The actual number of bytes in accept_buf to be sent.

 user_context

    OpenVMS usage:user_arg
    type:          quadword (Alpha and Integrity servers)
    access:       read only
    mechanism:    by value
    A user-specified value that is subsequently returned on any
    disconnect or data events on this connection.

 flags

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    ICC$M_SYNCH_MODE can be specified to indicate that the data
    transmission and reception routines $ICC_TRANSMIT, $ICC_RECEIVE,
    and $ICC_REPLY are allowed to return the status SS$_SYNCH in
    the case of synchronous completion, and that the AST will not be
    called.
