function converts the text form of an ACL referred to by
into the internal working structure for ACLs, appropriate for applying to
files or manipulating.
This function may cause memory to be allocated.
The caller should free any
releasable memory, when the new ACL is no longer required, by calling
as an argument.
Fx Ns 's
support for POSIX.1e interfaces and features is still under
development at this time.
Upon successful completion, the function shall return a pointer to the
internal representation of the ACL in working storage.
Otherwise, a value
shall be returned, and
shall be set to indicate the error.
If any of the following conditions occur, the
function shall return a value of
to the corresponding value:
Bq Er EINVAL
cannot be translated into an ACL.
Bq Er ENOMEM
The ACL working storage requires more memory than is allowed by the
hardware or system-imposed memory management constraints.
