DESCRIPTION

The function creates a new ACL entry in the ACL pointed to by the contents of the pointer argument On success, the function returns a descriptor for the new ACL entry via
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 acl_free(3) with 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 enabled. Any existing ACL entry descriptors that refer to entries in the ACL continue to refer to those entries.
