Progress callback functions
Progress callback functions give you feedback
about the progress of a task.
Normally, IBM® Cognos® TM1® API functions return immediately with a value. There are functions, however, that may take a long time to complete and which provide a periodic report on their progress. The feedback from such functions can be processed and displayed to the user using a progress callback function.
To setup a progress callback, use the function TM1SystemProgressHookSet.
To clear a previous progress callback, call the function TM1SystemProgressHookSet with a NULL pointer argument. See IBM Cognos TM1 functions for C for more information on using this function in C.
