Query regarding parent-child processes using wish in tcl windows

[adityai]

Hello,

I can successfully create child processes using wish83.exe in windows. When the child process exits, the parent process does not know that the child process did indeed exit. In my application, I need to let the parent process know that the child process exited, at the moment the child process exits.

Any suggestions?

How is the child process exiting? Is the user clicking something (that could be bound) or is the exit programmatic (that could be extended)? In either case, can you use "dde"?

SYNOPSIS
package require dde 1.2
dde servername ?topic?
dde execute ?-async? service topic ?data?
dde poke service topic item data
dde request ?-binary? service topic ?data?
dde services service topic ?data?
dde eval ?-async? service topic ?data?


DESCRIPTION
This command allows an application to send Dynamic Data Exchange (DDE) command when running under Microsoft Windows. Dynamic Data Exchange is a mechanism where applications can exchange raw data. Each DDE transaction needs a service name and a topic. Both the service name and topic are application defined; Tcl uses the service name TclEval, while the topic name is the name of the interpreter given by dde servername. Other applications have their own service names and topics. For instance, Microsoft Excel has the service name Excel.

or whatever equivalent on your platform?

Bong's suggestions are good..but I think you need something like twapi to grab the thread id , commit a join and, thus
synchronize threads.
Remember that in the modern win world everything is threaded
and the child/parent model is not really applicable.
