Detailed Description

The callback interface structure used to obtain changes in the interest set for a query.

The Query Callback interface.

All of the functions in this structure take a pointer to this structure (a DOFSystemQueryCallback) as their first argument. This structure may be placed as the first element in a larger structure that stores additional state, allowing the functions to access the additional state by casting the structure pointer to a pointer to the larger structure. If no additional state is required, this structure may be used directly.

Threading:

Functions in this interface may be called by multiple threads simultaneously. You must manage thread-safety.
