pci_get_slot(9)
NAME
pci_get_slot - locate PCI device for a given PCI slot
SYNOPSIS
struct pci_dev * pci_get_slot(struct pci_bus * bus,
unsigned int devfn);
ARGUMENTS
- bus
- PCI bus on which desired PCI device resides
- devfn
- encodes number of PCI slot in which the desired PCI device resides
and the logical device number within that slot in case of
multi-function devices.
DESCRIPTION
Given a PCI bus and slot/function number, the desired PCI device is
located in the list of PCI devices. If the device is found, its
reference count is increased and this function returns a pointer to its
data structure. The caller must decrement the reference count by
calling pci_dev_put. If no device is found, NULL is returned.
