I am just doing my first usage of OS/2 semaphores and I wish to create a
named mutex semaphore that will be shared between multiple processes.  I
have a few questions:

What happens if the process that creates the semaphore dies?  Anything?

What happens if the process that owns the semaphore dies?  Does it get
freed upon the death of the owner or do I need to do a DosReleaseMutexSem()
in the exit list?

What happens when all processes that use a semaphore die?  Does it disappear?  


If it does disappear when all processes close it then this presents a
problem for creating a semaphore.  I want to try and create a semaphore and
then if the return code indicates that it exists I want to open it.  What
if it disappears between the create and the open?  Would I have to try and
create it again?


  Thanks for your assistance.
