Hi All, I am having two processes and they are sharing shared-memory. - Process-1 (implemented in c++ and using boost::interprocess::managed_shared_memory interface) - Process-2 (implemented in c and using "she_open" and "mmap" interfaces) This code was working fine on Linux But When I deployed same code on FreeBSD. Process-2 (C lang based) is keep on throwing error in mmap. Error is "Bad file Descriptor". Please let me know: 1. Do I need to change the interface while moving from Linux to FreeBSD. 2. Is there any known issue with this design. Code Snippet: Process-1(c++): obj = new boost::interprocess::managed_shared_memory( boost::interprocess::open_or_create,<shm_name>, <shm_size>); // to create shm obj->allocate(<data_size>) ; // to write in shm Process-2 (c): int fd = shm_open(<shm_name>,O_RDWR, 0666);void * startpoint = mmap(NULL, <shm_size>, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); // using the startpoint to read data written by process-1. Boost version: Boost.1.63.0 I have raised same on stackoverflow.com and below is the link: https://stackoverflow.com/questions/48984703/boost-managed-shared-memory-not... Thanks, Vijay
