There are several functions that manage the memory associated with ACLs.
- acl_init()
- Allocate and initialize an ACL working storage area.
The argument to this function is the number of entries that you want in the list
(although acl_init() might allocate more).
It returns an acl_t pointer.
- acl_dup()
- Duplicate an access control list in working storage.
You pass it an acl_t pointer, and it returns a pointer to the copy of the list.
- acl_free()
- Free the working storage area allocated for an access control list (ACL) data object.
You should use this function to free the memory allocated by the other acl_*()
functions.
