    16 // Test the RSemaphore type.

    18 // RSemaphore
       
    19 // Details:
       
    20 // - Create two local semaphores, create a new thread, signal and wait on 
       
    21 // the semaphores numerous time. Kill the thread and verify results.
       
    22 // - Test creating a local semaphore with an initial count of -1. Verify 
       
    23 // failure results are as expected.
       
    24 // - Attempt to signal a semaphore without having done a create. Verify 
       
    25 // failure results are as expected.
       
    26 // - Attempt to signal a semaphore with signal count of -1. Verify failure
       
    27 // results are as expected.
