system(3) execve(2) popen(3) posix_spawn(2)
cp src -> dest, there are a lot of sub-api to copy data,
but in your case, you have only to spawn/exec/popen a pre-flight
script in your code and do whatever you want as everybody does
but I don't understand why you don't let the kexts into your app
bundle and then execute from CFBundle Resources directory your
pre-flight script using standard C functions
you can do whatever you want imagine you have your GUI app in
awakeFromNib just execute the load using popen on a pre-flight,
second option create a deamon script loader/unloader using launchd, I
don't understand what's your problem anyway
Cheers!
