We'll use a memory mapped file to provide the physical storage but shared memory works just as well. -<P> -Kirthika's abstract: -<UL> -The ACE_Malloc class is templatised by the type of memory pool -and the lock for it. The name of the memory pool provided can be used -in the "bind" call made by the server. This helps the other party -wanting to access it do so by a "find" call. The ACE_Malloc will -allocate -memory and on a "malloc" will return memory chunks from its reserve. -When the memory chunk is freed by the user, it will be appended to the -free list maintained by the class. Unless a "remove" is done explicitly, -the memory wont be returned to the OS. Various memory pool types can be -used, - ACE_MMap_Memory_Pool,ACE_Sbrk_Memory_Pool to name a few. -For further details: <A HREF="../../ace/Memory_Pool.h">ace/Memory_Pool.h</A>. -<P> -In this tutorial, a ACE_Malloc class with ACE_MMAP_MEMORY_POOL -and a semophore for syncronisation has been used. This is locked by -the server initially and released after it writes into it so that -the client waiting for it can go ahead and do its job. There is yet -another semaphore used by the server to exit only after the client -has finished its task, which is locked by the client at the start -and released when its done. -<P> -Some more information regarding memory management: -ACE also provides the ACE_Allocator class which uses -dynamic binding and is flexible, though at a cost of using -virtual pointer tables. Also, there is an ACE_Allocator_Adapter class -which has an ACE_Allocator interface but ACE_Malloc functionality. -<P> -Bottomline: Memory can be managed either using the ACE_Allocator -set of classes which uses polymorphism and is thus flexible but not as -efficient as the templatised version which is the ACE_Malloc set of -classes which are more efficient but not as felxible. - -</UL> <P><HR WIDTH="100%"> <CENTER>[<A HREF="../online-tutorials.html">Tutorial Index</A>] [<A HREF="page02.html">Continue This Tutorial</A>]</CENTER> |
