// Interfaces to the cIsThread class representing an OS-independent wrapper for a class that implements a thread.
|

|
|
// This class will eventually suupersede the old cThread class

/*
|
||
|
|
Usage:
|
||
|
|
To have a new thread, declare a class descending from cIsClass.
|
||
|
|
Then override its Execute() method to provide your thread processing.
|
||
|
|
In the descending class' constructor call the Start() method to start the thread once you're finished with initialization.
