Hi,

I know it is pretty simple to work out the services in the Linux box using a shell script (chkconfig --list) and easy to work out what package provides a service (rpm -qf /etc/init.d/servicename).

However, I am developing a C++ api to provide various attributes of a service and rpm packages.

For example, I have to provide information on the run levels a service starts, the services (facilities) that a service depend on and so on.

Similarly, I have to provide information on an installed rpm, almost all the information you get when you issue rpm -qi.

Is there a standard C++ way to do this? Or should it be done using the standard chkconfig and rpm -q?

Please let me know of the question is vague or you need more information in this regard.

Thanks

think twice about if it is useful and a good idea to re-invent the wheel and implement existing functionality that you can easy script (and possible call via system and process the result)

rpm has a C api

chkconfig is a perl script, so you can simple rewrite it in C(++) if you want.
by doing this you can see the calls it does and look what are the underlying c components for this.

ps:
it seems very distibution specific what you are going to do, so not general Linux

Thanks a4z. I was going to do this through parsing the results of the output. I just wanted to check whether there is a more standard way.

I understand that this is distro specific (obviously rpm). I am intending it to use it only on one distro. So it's fine.

Thanks
