( |
const struct rte_pci_addr * |
addr, |
|
|
char * |

|
|
size_t |
size |
|
) |
| |
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 |
◆ rte_pci_addr_cmp()
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.
◆ rte_pci_addr_parse()
int rte_pci_addr_parse |
( |
const char * |
str, |
|
|
struct rte_pci_addr * |
addr |
|
) |
| |
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
