VMS Help System Services, $ICC TRANSMIT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Sends a single message over a connection.

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

    Format

      SYS$ICC_TRANSMIT  conn_handle ,ios_icc ,[astadr] ,[astprm]

                        ,send_buf ,send_len

    C Prototype:

      sys$icc_transmit  (unsigned int conn_handle, struct _ios_icc

                        *ios_icc, void (*astadr)(__unknown_params),

                        __int64 astprm, char *send_buf, unsigned int

                        send_len);

    Arguments

 conn_handle

    OpenVMS usage:connection_id
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The handle of the fully established (open) connection to send the
    data over.

 ios_icc

    OpenVMS usage:ios_status_block
    type:         structure IOS_ICC
    access:       write only
    mechanism:    by 32-bit or 64-bit reference (Alpha)
    mechanism:    by 32-bit reference (VAX)
    I/O status block:

                           +2                       0
    -------------------------------------------------
    |       Undefined       |   Completion status   |
    -------------------------------------------------
    |                    Unused                     |
    -------------------------------------------------
                           +6                      +4

    Completion status values:

    SS$_NORMAL, SS$_EXQUOTA, SS$_INSFMEM, SS$_LINKABORT,
    SS$_LINKDISCON

 astadr

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

 astprm

    OpenVMS usage:user_arg
    type:         quadword (unsigned) (Alpha), longword (unsigned)
                  (VAX)
    access:       read only
    mechanism:    by 64-bit value (Alpha)
    mechanism:    by 32-bit value (VAX)
    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)
    mechanism:    by 32-bit reference (VAX)
    The 32-bit or 64-bit address (on Alpha systems) or the 32-bit
    address (on VAX 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_length
    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. The
    maximum transmission size is 1MB.
