PCI_GET_DEVICE(9) Hardware Interfaces PCI_GET_DEVICE(9)NAMEpci_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.
