Hello, "Using Shared Memory in Real-Time Linux" tells me that the maximum number of FIFOs is declared in "rt_fifo_new.c", but I can't find that file. Is it out of date?. I'm using RTLinux 2.2. Thank you. -- Ivan Martinez (Rodriguez) Bch in Computer Science - MSc student http://www.student.dtu.dk/~u990873 "Got fabes?"
