No, simply typedef'ing the struct still exposes the size and internal
layout to callers unless you do:
typedef struct pw_policy *pw_policy_t;
in the public header file and declare pw_policy ONLY in pw_policy.c.
In this case, you still need to use malloc to allocate the structure
on behalf of the caller.
I still prefer having the typedef, because I think that's a cleaner
way to pass around pointers to opaque data types.
