Utility function to write a pci device name, this device name can later be used to retrieve the corresponding rte_pci_addr using rte_pci_addr_parse().

Parameters

addr The PCI Bus-Device-Function address
output The output buffer string
size The output buffer size

Utility function to compare two PCI device addresses.

Parameters

addr The PCI Bus-Device-Function address to compare
addr2 The PCI Bus-Device-Function address to compare

Returns

0 on equal PCI address. Positive on addr is greater than addr2. Negative on addr is less than addr2, or error.

Utility function to parse a string into a PCI location.

Parameters

str The string to parse
addr The reference to the structure where the location is stored.

Returns

0 on success <0 otherwise
