----------------------------------------
Damitha,
This is definitely a good approach to have been taken. However, if we are to
adopt this approach, we'll have to use an interface identifier when requesting
for a particular instance. However, as you say, we can simply use the dll_type
as the identifier. And, thus a single dll can have multiple dll types, which is
acceptable. Therefore, instead of having the core to scan through the list of
entry points, we can simply use the get instance qualified by the interface id
(the dll type) to retrieve the appropriate entry point.
Regards,
Senaka

> it will be convenient for a single DLL to implement multiple interfaces. For

> Therefore the following approach is suggested
> typedef struct axis2_entry_point {
> const char *dll_type;
> CREATE_FUNCT create_funct;
> } axis2_entry_point_t;
> Then instead of axis2_get_instance, the DLL would have something like:
> const axis2_entry_point_t *axis2_get_entry_points(void)
> where the return value is a list terminated by a NULL dll_type.
