|
*
|
|
* Verify that statvfs() fails with:
|
|
* - EFAULT when path points to an invalid address.
|
|
* - ELOOP when too many symbolic links were encountered in translating path.
|
|
* - ENAMETOOLONG when path is too long.
|
|
* - ENOENT when the file referred to by path does not exist.
|
|
* - ENOTDIR a component of the path prefix of path is not a directory.
