Hello, is thare any posibility to use Qnet with shared memory between two devices via ethernet ? I have a problem with mmap memory. I'm using QNX 6.5 SP1 master have data at shared memory fd=shm_open(/net/master_name./dev/shmmem/database/test, O_RDWR,0777); //ok ftruncate(fd,sizeof(test_db)); //ok mmap(0,struct_size,PROT_READ | PROT_WRITE, MAP_SHARED,fd,0); //return (-1) :(
Hello, One of the limitations of qnet is that you can only access a shared memory object on the same machine it was created. But you could instead use a server to manage the shared memory on the remote note and have your client interact with it via messages. For more details on the limitations of qnet please check out: http://www.qnx.com/developers/docs/6.5.0_sp1/index.jsp?topic=%2Fcom.qnx.doc.neutrino_prog%2Fadv_qnet_topics.html&cp= 13_7_13_4&anchor=WHATWRWHATNT
