Hi all,
Is there an officially accepted way for a process to determine how
it was started?
It's easy to tell if it started from WB or CLI. But how does it know
if it was started from another Process (which PutMsg'ed a WBStartup to get
it going)?
I have a suite of programs that can be individually launched from CLI
or WB, or from a master control program which orchestrates the whole suite.
In each slave program I check pr -> CLI to see if it was launched from CLI,
If not I assume it was launched from either WB or the master program. Here
is my question:
How should the new process determine if it was started from WB or
from another application process?
In the master program all ports are created without names so that multiple
master programs/suites can be run concurrently without name collisions.
What I've been doing is:
strcmp(WBStartup.sm_Message.mn_ReplyPort -> mp_Node.ln_Name, "Workbench")
If a match, assume WB launched us, otherwise assume the master program
launched us. Is this safe? Or is there a better way?
Thanks for any help you can give.

Have you tried putting data in the WBStartup message or WBArg list that tells the process that it was started by your control program? -- -- Ken Farinsky - CATS - (215) 431-9421 - Commodore Business Machines uucp: ken@cbmvax.commodore.com or ...{uunet,rutgers}!cbmvax!ken bix: kfarinsky

/* launched by WB */
else
/* launced by control process */
Is this safe? Or is there a better way?
