windows - Why would WaitForSingleObject return WAIT_FAILED

Question

MSDN says

If the function fails, the return value is WAIT_FAILED. To get extended error information, call GetLastError.

The code is:

HANDLE     m_mutex_handle;    /**< m_mutex_handle. The handle to the created mutex. */
m_mutex_handle = ::CreateMutex( 0, false, NULL );
::WaitForSingleObject( m_mutex_handle, INFINITE );

But what are the reasons that could happen?

Answer 1

If you lack the SYNCHRONIZE privilege on the object, then you cannot wait. WAIT_FAILED will be returned.
