MultithreadingSampleProviderMain.cpp is the source file which contains theprovider entry point routine.2. MultithreadingSampleProvider.cpp [h] are the main provider sources thatimplement the MultithreadingSampleClass.3. The Base class has 3 derived classes called ThreadSampleOne, ThreadSampleTwoand ThreadSampleThree.4. ThreadSampleOne class instances are created inside the enumerateInstances method of the provider. After the instances creation this method calls explicitly the CreateThread function, which spawns a new sub-process and executes the command line cim client CLI.5. The additional functions added in the provider source program other than the standard methods are:CreateThread() - Function creating the sub-process (by using fork())reader() - child process reads from the input streamwriter() - Parent process writing to the output streamThis test program is currently tested only on Linux and AIX (on x86 arch.).It might not be working on non-unix platforms because of the usage of platformspecific system calls like fork(), and sleep();The parent process after writing to the output stream sleeps in the functionwriter() which makes the CLI command give a timeout error.TEST the Provider Working-------------------------1. Run the following command for checking the working of this provider:CLI niall -n root/SampleProvider ThreadSampleOne2. Run "TestClient" program present in the pegasus sources (to check for thenew classes registered by any new providers) as follows:	TestClient --n root/SampleProvider[You need to make sure that the TestClient is run for the SampleProvider repository because by default it runs only for root/cimv2]
