Function-Level Deinitialization Function

PowerCenter calls this function once for each function level to deinitialize any structure related to the custom function.

Use the following syntax:

INFA_EXPR_STATUS (*function_deinit) (INFA_EXPR_FUNCTION_HANDLE function);

Argument	Datatype	Input/ Output	Description
fnInstance	INFA_EXPR_FUNCTION_HANDLE	Input	Function-level handle that the framework passes to the plug-ins when the function instance-level init function is called.

The return datatype is INFA_EXPR_STATUS. Use ISUCCESS and IFAILURE as the return values. If the function returns IFAILURE, the session or workflow fails.
