/*
|
|
* Test Name: fremovexattr02
|
|
*
|
|
* Test cases::
|
|
* 1) fremovexattr(2) fails if the named attribute does not exist.
|
|
* 2) fremovexattr(2) fails if file descriptor is not valid.
|
|
* 3) fremovexattr(2) fails if named attribute has an invalid address.
|
|
*
|
|
* Expected Results:
|
|
* fremovexattr(2) should return -1 and set errno to ENODATA.
|
|
* fremovexattr(2) should return -1 and set errno to EBADF.
|
|
* fremovexattr(2) should return -1 and set errno to EFAULT.
