Routine-State Information

When the routine manager executes a C UDR, it puts information about the routine sequence for the UDR in an MI_FPARAM structure and passes this MI_FPARAM structure as the last argument to the UDR. From the MI_FPARAM structure, the UDR can obtain the following information:

• The number and data types of its arguments
• The assumed data type of its return value (for a user-defined function only)
• Any user data associated with the UDR

For information about how the routine manager executes a UDR, see Executing a UDR. For information about how to access the routine-state information in the MI_FPARAM structure, see Accessing MI_FPARAM Routine-State Information.
