Find devices that have a specific class code
#include <hw/pci.h> int pci_find_class( unsigned long class_code, unsigned index, unsigned* bus, unsigned* dev_func );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pci_find_class() function determines the location of the nth PCI device or function that has the specified class code.
|You must successfully call pci_attach() before calling any of the other PCI functions.|
You can find all the devices having the same class code by making successive calls to this function, starting with an index of 0, and incrementing it until PCI_DEVICE_NOT_FOUND is returned.
