The reverse is true +// from the daemon's point of view. This is an interface for the +// Transaction system to work with the IPC daemon as its transport +// layer. +// tmTransactionManager (TM) - Manages the different queues. Maintains +// the queues neccessary for different clients. Receives messages +// from the tmIPCModule and passes message to the IPC daemon through +// the tmIPCModule. +// tmQueue - this class manages the transactions for the different areas +// of the profiles being shared. Broken down by functional area there +// will be a queue for prefs, cookies etc, but not for profileA and +// profileB, and not for pref_delete, pref_create, pref_change etc... +// tmTransaction - the actual transaction being shared with the different +// tmClients. It contains the type of transaction, which will equate with +// a type of queue in existance, the owner of the transaction (an IPC daemon ID) +// and the actual text message to be shared. +// +////////////////////////////////////////////////////////////////////////////// + +/// XXX some docs that need to be put somewhere: +// +// from tmqueue.cpp +// Docs - note that the status of the TM_ATTACH_REPLY is only for checking +// for TM_ERROR_FAILURE.
