int
acl_set_qualifier
(acl_entry_t
entry_d, const void
*tag_qualifier_p);
The acl_set_qualifier
() function is a POSIX.1e call that
sets the qualifier of the tag for the ACL entry entry_d
to the value referred to by tag_qualifier_p.
The acl_set_qualifier
() function returns the
value 0 if successful; otherwise the value -1 is returned and
the global variable errno is set to indicate the error.
The acl_set_qualifier
() function fails if:
- [
EINVAL
]
- Argument entry_d is not a valid descriptor for an
ACL entry. The tag type of the ACL entry entry_d is
not
ACL_USER
or ACL_GROUP
.
The value pointed to by tag_qualifier_p is not
valid.
- [
ENOMEM
]
- The value to be returned requires more memory than is allowed by the
hardware or system-imposed memory management constraints.
POSIX.1e is described in IEEE POSIX.1e draft 17.
POSIX.1e support was introduced in FreeBSD 4.0. The
acl_get_qualifier
() function was added in
FreeBSD 5.0.
The acl_get_qualifier
() function was written by
