Constructor & Destructor Documentation

SharedMem::SharedMem ( size_t volume )

Allocate

Attach

virtual SharedMem::~SharedMem ( )

virtual

Destroy shared memory page only if it is attached nowhere

virtual int SharedMem::attach_cnt ( )

virtual

Returns count of attached processes (users)

Reimplemented from ObjectIPC.

void SharedMem::coherency ( )

protected

Check coherency of shm_id and key()

virtual void* SharedMem::ptr ( )

virtual

Return address of page in local space with autoattachement

Implements MemBlock.

virtual void SharedMem::resize ( size_t volume )

virtual

Change size of page to new volume without any guarantee of saving data during resize

Implements MemBlock.

virtual size_t SharedMem::size ( )

virtual

Get size of allocated shmem page

Implements MemBlock.
