/*
|
|
* Test Name: llistxattr02
|
|
*
|
|
* Description:
|
|
* 1) llistxattr(2) fails if the size of the list buffer is too small
|
|
* to hold the result.
|
|
* 2) llistxattr(2) fails if path is an empty string.
|
|
* 3) llistxattr(2) fails when attempted to read from a invalid address.
|
|
* 4) llistxattr(2) fails if path is longer than allowed.
|
|
*
|
|
* Expected Result:
|
|
* 1) llistxattr(2) should return -1 and set errno to ERANGE.
|
|
* 2) llistxattr(2) should return -1 and set errno to ENOENT.
|
|
* 3) llistxattr(2) should return -1 and set errno to EFAULT.
|
|
* 4) llistxattr(2) should return -1 and set errno to ENAMETOOLONG.
