50 * \brief Progress callback function type
51 *
52 * Various RDB API functions may accept an optional progress function pointer.
53 * That progress function will be called by the API function on a regular basis
54 * to communicate the progress of the operation to the client application.
55 *
56 * Along with the function pointer a pointer to some user data may be provided
57 * to the API function. This pointer will then be provided to the callback
58 * function which can use it to get or store some context information. Please
59 * note that the library doesn't use the user data in any way - it is just
60 * relayed from the caller to the progress callback function.
61 *
62 * It is guaranteed that the callback function is only called from within the
63 * API function (i.e. it is not called after the API function returned). But
64 * it is =NOT= guaranteed that the callback function is called from within the
65 * same thread context as the API function.
