/*
* A few points:
*
* Instead of returning an empty string array or empty integer array, we
* may return NULL.
*
* Free the data the library returns with libc free(). String arrays
* are NULL terminated, and you need to free the array itself in
* addition to the strings contained.
*
* We return error codes as negative errno, kernel-style. On success, we
* return 0 or positive.
*
* These functions access data in /run. This is a virtual file system;
* therefore, accesses are relatively cheap.
*
* See sd-network(3) for more information.
