acl_gen_entry(3)
specifically:
If the value of entry_id is ACL_FIRST_ENTRY, then the function will
return in entry_p a descriptor for the first ACL entry within acl. If a
call is made to acl_get_entry() with entry_id set to ACL_NEXT_ENTRY when
there has not been either an initial successful call to acl_get_entry(),
or a previous successfull call to acl_create_entry(), acl_delete_entry(),
acl_dup(), acl_from_text(), acl_get_fd(), acl_get_file(), acl_set_fd(),
acl_set_file(), or acl_valid(), then the result is unspecified.
Hopefully this helps.
