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.
If the ACL working storage cannot be increased in the current location,
then the working storage for the ACL pointed to by
may be relocated and the previous working storage is released. A pointer to
the new working storage is returned via
The components of the new ACL entry are initialized in the following ways: the
ACL tag type component contains ACL_UNDEFINED_TAG, the qualifier component
contains ACL_UNDEFINED_ID, and the set of permissions has no permissions

continue to refer to those entries.
Rv -std acl_create_entry
If any of the following conditions occur, the
to the corresponding value:
