System V - Memory Resize

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 

Can we resize the memory (allocated using System V shmget() function call)

I know that we can remap the memory in Posix Shared memory using mremap system call.

What about System V implementation?

If we resize the memory (allocated using System V shmget() function ) can we resize it using mremap(), I think we can, but it will not make changes to the internal data structures of System V implementation in Kernel.

 

What you all say?
