acl_get_permset

DESCRIPTION¶
The

Any ACL entry descriptors that refer to the entry referred to by
entry_d shall continue to refer to those
entries.

The
acl_get_permset
() function returns the
value 0 if successful; otherwise the value -1 is returned and
the global variable
errno is set to indicate
the error.
ERRORS¶
If any of the following conditions occur, the
acl_get_permset
() function returns
-1
and sets
errno to
the corresponding value:
- [
EINVAL
]
- The argument entry_d is not a valid
descriptor for an ACL entry.
