Since the Amiga gives us such a nice multitasking environment, I'd like to take advantage of it from within a program. From what I've read - there are two methods to do this: task and process. A task would be great for what I need, but it doesn't allow I/O or AmigaDOS calls from within. A process isn't great since I would like the 'child' to share resources with the 'parent', and don't want 2 seperate exectables. What I really need is something like SYS$DCLAST - ie. Launch a routine asynchronously given the routine name, a parameter, and a mode. What I really want to do is create a 'task/process' to gather user input, while the 'parent' continues it's calculations. The two could communicate through a shared MsgPort or (simpler) by using a small region of global memory. Does a similar function exist? I would certainly hope so. Steve

Have you looked into the EXEC CreateProc() function or Lattice C's fork()? CreateProc() takes some creative hacking to get it to execute in the parent's context... Lattice's fork() isn't too good since it really doesn't match the Unix version too well. You might even check out IPC (Inter Process Communication) by Pete Goodeve and Peter da Silva on Fish #290. If you really want $DCLAST behaviour (i.e. Software Interrupt) then check out the EXEC interrupt handeling functions... John | |||||

I don't know what I was thinking but I don't really need $DCLAST. (I've had AST's on the brain lately :^) CreateProc() offers similar functionality to $CREPRC, but neither is really what I need. I need a task w/AmigaDOS functionality. (Perhaps a 'thread'?) I think my best bet would be to make use of CreateProc() and pass messages to the 'parent'. It's more work than I wanted to do, but it's probably the best thing to do. Will keep researching it. Thanks, Steve | |||||
