Re: [Boost-users] [Boost Interprocess] - Shared Memory File - Corruption

Hi, I am a little confused about how to make 'interprocess_mutex' part of the 'managed_shared_memory' object which actually represents the shared_memory? Is there a base class or something that can take the mutex? I placed an '*interprocess_mutex*' as a member variable *in the class that contains my 'managed_shared_memory'* object as a member variable and was locking it in the methods that accessed the shared memory. I guess this did not work out as I believe what I did effectively locked the object of my class that was holding the embers. And since this is not actually the shaed resource between the processes it didn't work out.. I'd really appreciate if you could provide an example of just show me bbased on my initial code.. how the 'managed_shared_memory' can be locked using the mutex.

Hi Ion, Probably that's the reason.. I haven't used any mutexes thought it's all implemented in the 'interprocess'. I am kind of new to this stuff.. Could please give me a code example where 'interprocess_mutex' is used by a 'Server' and 'Client' to lock the managed_shared_memory ?

I really appreciate your help.

Thanks & Regards Sreenu

I don't see any problem with your approach, can you give me more information? Also, take in care that you need to use mutexes to protect concurrent accesses to the list (an interprocess_mutex constructed in the segment should work).
