How does a new CLI inherit its path?
Here's what I found by experimenting. It appears a script can modify the
path for the CLI executing it, other CLIs are not affected. If you start a
new CLI from an existing CLI, the new CLI appears to inherit the existing
CLI's path. It also appears that CLIs started from POPCLI aren't getting the
path that was set in s:startup-sequence. CLIs started by the workbench do
get the path that was set in s:startup-sequence.
POPCLI is a utility supplied with the lattice C compiler that will blank the
screen and run a specified command when L-ESC is pressed.

If you are in a CLI, and do a newcli, the child CLI will have a copy of the parents. Simple, right ? Then there's workbench. When Workbench fires up via LoadWB, it snapshots the paths in effect in that shell. This is the paths that get copied when starting a shell from workbench, ie from the CLI icon, or from tools like PopCLI. andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.

Makes sense, each process inherits its parent's attributes. Generally this is the same thing of course because startup sequences would have a bunch of path assignments etc, then the background processes such as PopCLI and LoadWB get fired off. > andy >-- >andy finkel {uunet|rutgers|amiga}!cbmvax!andy >Commodore-Amiga, Inc. > >"God was able to create the world in only seven days because there > was no installed base to consider." ^- love that quote. > >Any expressed opinions are mine; but feel free to share. >I disclaim all responsibilities, all shapes, all sizes, all colors. -- |_o_o|\\ |. o.| || The Jay Denebeim | . | || Software | o | || Distillery | |// Address: mcnc!wolves!deepthot ====== BBS:(919)-460-7430 VOICE:(919)-460-6934

But I was interested in the mechanism by which the inheritance takes place. How can a program I write discover what the path is. How can a program I write pass a new path onto a CLI it starts up? * * * \|/ * _______ --O-- ____/ KC1VP \____ * /|\ * ______/ (203) 389-8680 \______ ______/ Eggplant Software Tools \________ ______/ 95 Fountain Terr., New Haven, CT, USA, 06515 \_______ / Chris Hind Genly chris@genly.uucp uunet!hsi!genly!chris \ ----------------------------------------------------------------

DOS (or under 1.3 the Shell) copies the path list for the new CLI process, if it was started from a CLI process. The path list is hanging off your CLI process structure, and is basically a lined list of Locks. andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
