Define the pointer to the error handling function.

Description:

This API is used to define the pointer to the error handling function.

注意

• None.

参数

fileName	[IN] Log file that stores error information.
lineNo	[IN] Line number of the erroneous line.
errorNo	[IN] Error code.
paraLen	[IN] Length of the input parameter pPara.
para	[IN] User label of the error.
