96 support for POSIX.1e interfaces and features is still under
97 development at this time.
99 Upon successful completion, the function shall return a pointer to the ACL

123 The ACL type passed is invalid for this file object.

143 POSIX.1e is described in IEEE POSIX.1e draft 17.

152 POSIX.1e support was introduced in
