Hi,
I want to do insmod and rmmod from a function. This is because, i want to load a different driver version for some of the conditions i have. To do this, i need to invoke rmmod and insmod from the function, how can i do this?I am using linux kernel 2.6.
thanks in advance,
-Shashi

a common way is to fork() then use then use something in the exec() family
like
execvp(program, args);

since modprobe and freinds only run as root depending on what you are doing if you are regular user you can use sudo..
in a production environment this would be a bad thing because funky kernel modules are a way for people to compromise your system
