I've recently rehosted some Ms/Dos code to a sun386i. The code speaks to a memory mapped board in the AT bus of the sun. I'm using mmap to map in the address space of this board. My board has a TI34010 graphics processor on it. My current Ms/Dos software acts as a stub-server with the TI34010 as a client to provide basic system calls (open, close, read, write, etc). I want to fork and run another task as a debugger for the TI34010. I need a good efficient way to moderate access to the board (essentially a semaphore). So I'll run two tasks (the debugger and the stub-server) using the semaphore. A simple example with code is what I'm looking for. I'm aware there are a wide variety of system services on SunOS to do IPC -- I need some advice on which one is what I want. marty ARPA: leisner.henr@xerox.com GV: leisner.henr NS: martin leisner:wbst139:xerox UUCP: hplabs!arisia!leisner
