NAME

6       pci_get_device - begin or continue searching for a PCI device by
7       vendor/device id
8

SYNOPSIS

10       struct pci_dev * pci_get_device(unsigned int vendor,
11                                       unsigned int device,
12                                       struct pci_dev * from);
13

ARGUMENTS

15       vendor
16           PCI vendor id to match, or PCI_ANY_ID to match all vendor ids
17
18       device
19           PCI device id to match, or PCI_ANY_ID to match all device ids
20
21       from
22           Previous PCI device found in search, or NULL for new search.
23

DESCRIPTION

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