When an application crashes...

Hi all,

I'm working on a Linux machine and using g++. I'm developing an
semaphore module for a number of applications in the system.

My question scenario is, an application can lock a resource which is
shared memory segment in this case, after they locked a segment and if
they somehow crash then the lock won't be released because the
application locked the resource is dead.

I hope there must be a way to release the lock so solve this problem
even the application is crashed unexpectedly.

Any idea?

best regards,

Alex D. B. Kim
