Fellow Amigans:
I would like some advice/examples on how to set up several functions
in a source code file as independent processes (using ports and messages
for inter-process communications.) My problem can be described as follows:
main()
{
/* brilliant code inserted here...*/
}
func_1()
{
}
func_2()
{
}
I would like to set up func_1 and func_2 to run as completely independent
processes. Also, After they are set up, is anything needed to get them to
actually start executing? I have a project now where the tasks are being
set up correctly (even show up with TaskX), but they seem to never actually
execute. Any suggestions?

The basic information in the article is: 1. Use CreateProc() to start a new process. 2. CreateProc() takes a BPTR to a seglist, so you have to create a fake seglist which points to the function that you wish to turn into a process. 3. You can use the message port in the process structure for syncronization between the two processes. I would recommend getting the whole article. Under 2.0, you can use CreateNewProc() to do the same thing without the fake seglist. -- -- Ken Farinsky - CATS - (215) 431-9421 - Commodore Business Machines uucp: ken@cbmvax.commodore.com or ...{uunet,rutgers}!cbmvax!ken bix: kfarinsky
