   Completion status values:

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.
