Routine Description:

    Ownership of a mutex object can be released with the ReleaseMutex
    function.

    A mutex object can only be released by a thread that currently owns
    the mutex object.  When the mutex is released, the current count of
    the mutex object is incremented by one.  If the resultant count is
    one, then the mutex object is no longer owned.  Any threads that are
    waiting for the mutex object are examined to see if their wait can
    be satisfied.

Arguments:

    hMutex - An open handle to a mutex object.  The handle must
        have MUTEX_MODIFY_STATE access to the mutex.

Return Value:

    TRUE - The operation was successful

    FALSE/NULL - The operation failed. Extended error status is available
        using GetLastError.
