My question is as well as simple and newbie - what happens to the installed RPM packages? I mean do they get inserted into the linux kernel like common modules? Or the wait to be referenced untill they are needed? And if so, how can one access the functionality provided by the module?
Well, it is not one question actually. I'm in the following situation:
I have to write a simple programm which accesses VME bus and does some read/write and checks of the boards on the VME bus. But I cannot come up with as to how to reference the VME bus in my programm. There are a lot of packages already installed on the system related to VME (after all the whole filesystem is mounted on a SCSI hard drive which is on the VME bus) but how do I get use of their functionality in a custom program? Here is what I got:
[root@host root]# rpm -qa | grep vme
Anybody has an idea how to get use of the installed packages? There must be also libraries with predefined functions for VME bus read/write/interrupt/etc. but I can't locat them either... Please help if you can
