Scanning the PCI config space from a C application
I have not programmed in a unix like system for a while now, I need to scan the pci config space in order to display specific properties associated with my device. Is there an API that allows me to scan the pci configuration space and read specific register offsets? Can I access the pci config space using the 0xCF8 and 0xCFC IO port registers, if an API doesn't exist? I need to do this within a C application. To be specific I would like to do the same thing lspci does.
I've never gotten involved with that, but a little googling suggests that you'll get a wealth of information by downloading this, exploding and "make"ing the software, reading the resultant man page, and browsing through the source.
