SYNOPSIS

9       struct pci_dev * pci_get_class(unsigned int class,
10                                      struct pci_dev * from);

ARGUMENTS

13       class
14           search for a PCI device with this class designation
15
16       from
17           Previous PCI device found in search, or NULL for new search.

DESCRIPTION

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