// A class which groups functions dealing with connecting to the network from a
|
||||
// workstation using dial-up access to the net. There is at most one instance
|
||||
// of this class in the program accessed via GetDialUpManager().

/* TODO
|
||||
*
|
||||
* 1. more configurability for Unix: i.e. how to initiate the connection, how
|
||||
* to check for online status, &c.
|
||||
* 2. add a "long Dial(long connectionId = -1)" function which asks the user
|
||||
* about which connection to dial (this may be done using native dialogs
|
||||
* under NT, need generic dialogs for all others) and returns the identifier
|
||||
* of the selected connection (it's opaque to the application) - it may be
|
||||
* reused later to dial the same connection later (or use strings instead of
|
||||
* longs may be?)
|
||||
* 3. add an async version of dialing functions which notify the caller about
|
||||
* the progress (or may be even start another thread to monitor it)
|
||||
* 4. the static creation/accessor functions are not MT-safe - but is this
|
||||
* really crucial? I think we may suppose they're always called from the
|
||||
* main thread?
