Even though we currently allow a FIFO to be opened for reading only once, we can still have more than one reader open because of dup and fork. Add a named shared memory section accessible to all readers of a given FIFO. In future commits we will add information needed by all readers to this section Add a class fifo_shmem_t that lets us access this information. Add a method create_shmem that is called when a reader opens, and add a method reopen_shmem that is called by dup, fork, and exec. (Each new reader needs its own view of the shared memory.) |
