/*
|
|
* Test Name: flistxattr02
|
|
*
|
|
* Description:
|
|
* 1) flistxattr(2) fails if the size of the list buffer is too small
|
|
* to hold the result.
|
|
* 2) flistxattr(2) fails if fd is an invalid file descriptor.
|
|
*
|
|
* Expected Result:
|
|
* 1) flistxattr(2) should return -1 and set errno to ERANGE.
|
|
* 2) flistxattr(2) should return -1 and set errno to EBADF.
