-/*============================================================
-**
-** Source: CreateMutexA_ReleaseMutex/test2/CreateMutexA.c
-**
-** Purpose: This test case tests the following things
-** - Creation of named Mutexes
-** - Creating multiple handles to a single named Mutex
-** - Ensuring that these handles work interchangeably
-** - Setting bInitialOwnerFlag to TRUE will cause the
-** initial call to a Wait function on the same Mutex
-** to actually wait.
-** - Waiting on a Mutex that a thread already owns does
-** not block.
-** - Create Named mutex with empty string ("")
-** - Create Named mutex with string of MAX_LONGPATH length
-** - Calling RelaseMutex with invalid Mutex handles and
-** valid but unowned Mutexes.
-**
-** Dependencies: CreateThread
-** ReleaseMutex
-** WaitForSingleObject
-** CloseHandle
-** Sleep
-** memset
-**
