I have an application in development. I am using semaphore.h to create
some named semaphores using sem_open.
Unfortunately, my semphores were not gracefully cleaned up and now when
I try and run my application I get a segfault when I try and access the
named semaphore.
Is there a command I can use to delete all of these orphaned
semaphores?
Thanks!
