Re: [MACTCL] Execl

[Michael M. <mic...@na...>]

What I'm doing, in a nutshell, is building a wrapper inside an application
bundle that accepts user inputs, then launches a new program based upon
those inputs while still running within the framework of the bundle.

I can do this with a shell script.  For instance, if I specify a shell
script as my CFBundleExecutable, and it contains the following lines:

    #!/bin/sh
    exec MyProgram

Then MyProgram will take over from the shell script and the O/S thinks that
all is still well with the app (icon stays in the dock, menus are still
active, etc.).  However, if my CFBundleExecutable is a Tcl/Tk script
containing the following:

    exec MyProgram &
    destroy .

Then MyProgram will launch just fine, but the "destroy ." command seems to
tell the O/S that the app has terminated.  In other words, the icon
disappears from the dock, menus go away, etc.

I think that execl would provide an equivalent to the shell "exec" command,
but unfortunately it's not implemented for the Mac.
