Sends a single message over a connection.
On Alpha and Integrity server systems, this service accepts 64-
bit addresses.

,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);
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 and Integrity
servers)
I/O status block:

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_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.
