Local Interface Names and IndexesName-to-Index |
|
The first function maps an interface name into its corresponding index.
If the specified interface name does not exist, the function returns a value of zero, and sets errno to ENXIO. If a system error occurred (such as running out of memory), the function returns a value of zero and sets errno to the proper value (such as ENOMEM). |
