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.
