Hi, I am having a Design/Implementation issue with Boost managed_shared_memory. Let me describe it: -------------------- Problem ------------------------- I am having two processes (i) Writer (ii) Reader Here Writer is a c++ executable which is using boost to write in shared memory. Code snapshot for writing method: shm_controller.reset(new boost::interprocess::managed_shared_memory( boost::interprocess::open_or_create, shmName, size));void * addr = shm_controller->allocate(size) ; shm_controller ->deallocate(addr); Once I have addr pointer, I am using memcpy to write in SHM. On other hand I am having Reader, which is C executable. They both are communicating via message passing application. I wrote Reader code in such way: Writer is passing address, which is stored in "addr" (from above code snapshot) to Reader. Once reader receive the address and size, I am using memcpy to write SHM data in Reader's local variable. Note1:- (This reader is not using any boost shm API, as it's C application ) Note2:- I validated address is same on Writer and reader (after communication). But reader's memcpy to read shm data is leading crash in my executable (reader). ------------------------------------------------------------- I need help in : 1) Can we use boost::interprocess::managed_shared_memory in C ?? 2) Is there any implementation problem in above section. (can't a reader access shm of writer via pointer) 3) Is there a way to solve this C and C++ limitation like any wrapper implementation etc. Please provide me any kind of help or pointers on this issue, as I am stuck with this and need to resolve it ASAP.
