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.
