Signal out from fork()'d shell script back to the C++ application

Hi,
I am writing a C++ application; in which at one point I fork() a new process, which executes a shell script (via execv() call).
Now the shell script can take a while to finish (tarring, burning a cd, etc.) and I would like to update the parent application about the progress (while the script is running).
Any ideas on how to do this?
Thank you!
Miro

NAME
Catalyst::Manual::Deployment::SharedHosting - Deploying Catalyst on Shared Hosting Catalyst on shared hosting So, you want to put your Catalyst application out there for the whole world to see, but you don't want to break the bank. There is an answer - if you can get shared hosting with FastCGI and a shell, you can install your Catalyst app in a local directory on your shared host. First, run perl -MCPAN -e shell and go through the standard CPAN configuration process. Then exit without installing anything. Next, download the latest local::lib package and follow its 'bootstrap' instructions to get it installed and the local configuration added to your "~/.bashrc". Now log out, then back in again (or run ". .bashrc" if you prefer). Now you can install the modules you need using CPAN as normal; they will be installed into your local directory, and Perl will pick them up. Finally, change into the root directory of your virtual host, and symlink your application's script directory: cd path/to/mydomain.com ln -s ~/lib/MyApp/script script And add the following lines to your .htaccess file (assuming the server is setup to handle .pl as fcgi - you may need to rename the script to myapp_fastcgi.fcgi and/or use a SetHandler directive): RewriteEngine On RewriteCond %{REQUEST_URI} !^/?script/myapp_fastcgi.pl RewriteRule ^(.*)$ script/myapp_fastcgi.pl/$1 [PT,L] Now "http://mydomain.com/" should now Just Work. Congratulations, now you can tell your friends about your new website. AUTHORS
