PCI_GET_DEVICE(9)                      Hardware Interfaces                      PCI_GET_DEVICE(9)



NAME
       pci_get_device - begin or continue searching for a PCI device by vendor/device id

SYNOPSIS
       struct pci_dev * pci_get_device(unsigned int vendor, unsigned int device,
                                       struct pci_dev * from);

ARGUMENTS
       vendor
           PCI vendor id to match, or PCI_ANY_ID to match all vendor ids

       device
           PCI device id to match, or PCI_ANY_ID to match all device ids

       from
           Previous PCI device found in search, or NULL for new search.

DESCRIPTION
       Iterates through the list of known PCI devices. If a PCI device is found with a matching
       vendor and device, the reference count to the device is incremented and a pointer to its
       device structure is returned. Otherwise, NULL is returned. A new search is initiated by
       passing NULL as the from argument. Otherwise if from is not NULL, searches continue from
       next device on the global list. The reference count for from is always decremented if it
       is not NULL.
