/*
|
|
|
|
* 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
|
2014-03-25 04:14:28 +01:00
|
|
|
* are NULL terminated, and you need to free the array itself in
|
2014-02-27 01:24:05 +01:00
|
|
|
* addition to the strings contained.
|
|
|
|
*
|
2014-03-25 04:14:28 +01:00
|
|
|
* We return error codes as negative errno, kernel-style. On success, we
|
|
|
|
* return 0 or positive.
|
2014-02-27 01:24:05 +01:00
|
|
|
*
|
2014-03-25 04:14:28 +01:00
|
|
|
* These functions access data in /run. This is a virtual file system;
|
|
|
|
* therefore, accesses are relatively cheap.
