/*
|
|
* Test Name: fremovexattr01
|
|
*
|
|
* Description:
|
|
* Like removexattr(2), fremovexattr(2) also removes an extended attribute,
|
|
* identified by a name, from a file but, instead of using a filename path, it
|
|
* uses a descriptor. This test verifies that a simple call to fremovexattr(2)
|
|
* removes, indeed, a previously set attribute key/value from a file.
