strncpy() warning will go away in v10 after applying the comment from Thomas to modify it to strlcpy. getenv() is a bit tricky: a) The function it is being used in (rte_pci_get_sysfs_path) is a UNIX only function, from the usage of the function it seems getenv is safe to use. b) Changing to code to getenv_s, _dupenv_s or GetEnvironmentVariable would mean that the user will now need to handle a buffer to store the value of the environment variables. Do we want to modify it for rte_pci_get_sysfs_path and all of the call sites? Looks like we can ignore this warning in this case. > Do we have any test application to test with? dpdk-helloworld runs > successfully. You can use rte_bus_scan() inside rte_eal_init() to test the scanning process.
