3.7 Server Function of Transmitting a Message with
Confirmation
When an ordinary byte block read/write or word block read/write
service of the message transmission server function is executed, data
is exchanged with the client without user-program intervention.
Data can also be exchanged with user-program intervention using a
specific virtual address space specification.
This specification can be used to establish the concurrency of data
tens to hundreds of bytes long easily. In this case, the user program
must transmit a response message, however.
This section details the interfaces used for transmission and reception
using the function of transmitting a message with confirmation.
These interfaces use the transmission and reception areas for
transparent message transmission.
To perform transmission of a message with confirmation, specify an
address with an offset of 1000000h in the ordinary virtual address
space.
