Multithreading Multi-Threaded Programming

Using Three Synchronization Classes
} As an example, take an application that maintains a linked list of
accounts.
} This application allows up to three accounts to be examined in separate
windows,
} but only one can be updated at any particular time. When an account is
updated, the updated data is sent over the network to a data archive.
} This example application uses all three types of synchronization
classes.
} Because it allows up to three accounts to be examined at one time, it
uses CSemaphore to limit access to three view objects. When an
attempt to view a fourth account occurs, the application either waits
until one of the first three windows closes or it fails.
} When an account is updated, the application uses CCriticalSection to
ensure that only one account is updated at a time.
} After the update succeeds, it signals CEvent, which releases a thread
waiting for the event to be signaled. This thread sends the new data to
the data archive.
