    BOOL bInheritHandle,
    DWORD dwThreadId
    )

/*++

Routine Description:

    A handle to a thread object may be created using OpenThread.

    Opening a thread creates a handle to the specified thread.
    Associated with the thread handle is a set of access rights that
    may be performed using the thread handle.  The caller specifies the
    desired access to the thread using the DesiredAccess parameter.

Arguments:

    mDesiredAccess - Supplies the desired access to the thread object.
        For NT/Win32, this access is checked against any security
        descriptor on the target thread.  The following object type
        specific access flags can be specified in addition to the
        STANDARD_RIGHTS_REQUIRED access flags.

        DesiredAccess Flags:

        THREAD_TERMINATE - This access is required to terminate the
            thread using TerminateThread.

        THREAD_SUSPEND_RESUME - This access is required to suspend and
            resume the thread using SuspendThread and ResumeThread.

        THREAD_GET_CONTEXT - This access is required to use the
            GetThreadContext API on a thread object.

        THREAD_SET_CONTEXT - This access is required to use the
            SetThreadContext API on a thread object.

        THREAD_SET_INFORMATION - This access is required to set certain
            information in the thread object.

        THREAD_SET_THREAD_TOKEN - This access is required to set the
            thread token using SetTokenInformation.

        THREAD_QUERY_INFORMATION - This access is required to read
            certain information from the thread object.

        SYNCHRONIZE - This access is required to wait on a thread object.

        THREAD_ALL_ACCESS - This set of access flags specifies all of the
            possible access flags for a thread object.

    bInheritHandle - Supplies a flag that indicates whether or not the
        returned handle is to be inherited by a new process during
        process creation.  A value of TRUE indicates that the new
        process will inherit the handle.

    dwThreadId - Supplies the thread id of the thread to open.

Return Value:

    NON-NULL - Returns an open handle to the specified thread.  The
        handle may be used by the calling process in any API that
        requires a handle to a thread.  If the open is successful, the
        handle is granted access to the thread object only to the
        extent that it requested access through the DesiredAccess
        parameter.

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