Obtaining user-state information in subsequent invocations of the UDR
About this task
To obtain user-state information in subsequent invocations of the UDR:
Procedure
- Use the mi_fp_funcstate() function to retrieve the user-state pointer from the MI_FPARAM structure.
- If the user-state pointer is not a NULL-valued pointer,
cast the pointer to the data type of your user-state information.
After the user-state pointer points to the correct data type, you can access the user-state information.
