|
|
|
|
A service may require gateway call to process special
|
|
requests received from the clients.
|
|
Such requests are processed by spawning a special process and communicating
|
|
with the special process. The process takes the client supplied data as
|
|
input and sends its output to be sent to the client.
|
|
Since the service module is aware of the details of input and output,
|
|
a special thread is created in the service process to deal with the
|
|
input and output. A two-way pipe is established b/w the spawned process
|
|
and the service thread.
|
|
Once the "special gateway process" completes processing the input and
|
|
terminates, the thread doing I/O proceeds to munging.
|
|
During munging state, the thread calls upon a callback function for
|
|
munging and data transfer. The call-back function is responsible
|
|
for altering the data if need be and sending the data to client.
|
|
After this the service thread terminates its work.

Description:
|
|
This function creates a gateway processor object responsible for processing

gateway requests. It extracts the parameters required from input request

package ( IGATEWAY_REQUEST structure). It creates a separate process for
|
|
gateway request and a separate thread for handling I/O for the
|
|
gateway request. The thread uses buffers supplied for i/o in pigRequest.
|
|
On a completion of read, the thread calls the callback function for
|
|
processing the data retrieved. If the call back function returns any error
|
|
further procecssing in the thread is halted and the thread dies.
|
|
The process also will eventually die, since the pipes are broken.

/*++
|
|
Description:
|
|
This is the core function that performs the I/O with the gateway process.
|
|
I/O is performed using the pipes created by cross-linking
|
|
the stdout and stdin of gateway process to duplicated handles in the I/O
|
|
thread.
|
|
|
|
First, this function writes any data to be sent to the gateway process
|
|
on the read pipe of the process
|
|
( to m_hStdOut of the IGATEWAY_PROCESSOR object).
|
|
|
|
Subsequently it loops receiving data from the gateway process and passing
|
|
it onto the client ( meaning service that requested gateway processing).
|
|
It uses the read callback function to make the client perform necessary
|
|
work.
|
|
At the least the client should copy the data returned during in callback.
|
|
( Otherwise, there is a danger of the data getting lost in subsequent
|
|
read from the gateway process.)
|
|
|
|
Arguments:
|
|
None
|
|
|
|
Returns:
|
|
Win32 error code.
