A pointer to the flAttr attribute flags that
were passed by DosCreateMuxWaitSem.
Possible flags are shown in the list below:
DC_SEM_SHARED
The semaphore is shared.
DCMW_WAIT_ANY
The semaphore waits for any event semaphore in the muxwait-semaphore list
to be posted, or for any mutex semaphore in the list to be released. When
any one of the semaphores is cleared, the thread that is waiting on the
muxwait semaphore can continue executing.
DCMW_WAIT_ALL
The semaphore waits for all of the event semaphores in the muxwait list
to be posted, or for all of the mutex semaphores in the list to be released.
When all of the semaphores are cleared, the thread that is waiting on the
muxwait semaphore can continue executing.
