PRInt32 tmQueue::PostTransaction ( tmTransaction aTrans  ) 

Places the transaction passed in on the queue. Takes ownership of the transaction, deletes it in the destructor. A reply is created and sent to the client to indicate the success of the posting of the transaction.

The reply is sent for all cases, with the status field containing the return value.

>= 0 if the message was posted properly.

-1 if the client posting is not attached to this queue, if the transaction has been posted to the wrong queue or if an error occured when trying to add the post to the internal storage.
