Function Documentation void rte_pci_device_name (const struct rte_pci_addr * addr, char * output, 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 int rte_pci_addr_cmp (const struct rte_pci_addr * addr, const struct rte_pci_addr * addr2) 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. Nega- tive on addr is less than addr2, or error. 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 Author Generated automatically by Doxygen for DPDK from the source code. Version 25.11.0 Thu Aug 27 2026 rte_pci.h(3)
