 astadr

    OpenVMS usage:ast_procedure
    type:         procedure_entry_mask
    access:       call without stack unwinding
    mechanism:    by 32-bit or 64-bit linkage reference (Alpha and
                  Integrity servers)
    The AST routine to be executed when the operation completes.

 astprm

    OpenVMS usage:user_arg
    type:         quadword (unsigned) (Alpha and Integrity servers)
    access:       read only
    mechanism:    by 64-bit value (Alpha and Integrity servers)
    The parameter to be passed to the AST routine.

 send_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)
    The 32-bit or 64-bit address (on Alpha and Integrity server
    systems) of the buffer containing the data to be sent. The length
    of this buffer is specified by the argument send_len.

 send_len

    OpenVMS usage:buffer size
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The length (in bytes) of the data to be sent over the connection.
    This value specifies the length of the buffer send_buf.

    IOS_ICC Arguments:

 returned_data_len (output)

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value
    This parameter is passed through the ios_icc. The $ICC_TRANSCEIVE
    service writes the actual length (in bytes) of the reply data
    received into offset ios_icc$l_txrcv_len of the ios_icc. This
    value represents how much data in reply_buf was returned by the
    target application.

 reply_buf (input)

    OpenVMS usage:byte_stream
    type:         character-coded text string
    access:       write only
    mechanism:    by 32-bit or 64-bit reference (Alpha and Integrity
                  servers)
    This parameter is passed through the ios_icc. The 32-bit or 64-
    bit address (on Alpha and Integrity server systems) of the buffer
    available to receive the incoming reply message is placed in
    offset ios_icc$a_reply_buffer of the ios_icc.

 reply_buf_len (input)

    OpenVMS usage:buffer_size
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    This parameter is passed through the ios_icc. The length (in
    bytes) of the buffer to receive the reply message. This value
    specifies the length of the buffer reply_buf. This value is
    placed in offset ios_icc$l_txreply_len of the ios_icc.
