How to load Linux kernel modules from C code?

Question

I have an application that has both two external kernel modules and a userspace daemon. I want to load the modules from the daemon code, written in C, at startup, and unload

Answer 1

I'm not sure there's a cleaner way than system.

But for sure, if you want to load/unload the modules from your userspace daemon, then you force yourself to run the daemon as root*, which may not be considered as secure.

*: or you can add the explicit commands in the sudoers file, but this will be a nightmare to manage when deploying your application.
