26 | * A few points: | |
27 | * | |
28 | * Instead of returning an empty string array or empty integer array, we | |
29 | * may return NULL. | |
30 | * | |
31 | * Free the data the library returns with libc free(). String arrays | |
10b17992 | 32 | * are NULL terminated, and you need to free the array itself in |
fe8db0c5 TG |
33 | * addition to the strings contained. |
34 | * | |
10b17992 JSJ |
35 | * We return error codes as negative errno, kernel-style. On success, we |
36 | * return 0 or positive. | |
fe8db0c5 | 37 | * |
10b17992 JSJ |
38 | * These functions access data in /run. This is a virtual file system; |
39 | * therefore, accesses are relatively cheap. | |
