Using Input and Output Parameters

Business functions frequently return error codes and pointers. The input and output parameters in the business function data structure should be named as follows:

Input and Output Parameter	Description
cReturnPointer	When allocating memory and returning GENLNG.
cErrorCode	Based on cCallType, cErrorCode returns a 1 when it fails or a 0 when it succeeds.
cSuppressErrorMessage	If the value is 1, do not display error message using jdeErrorSet(...). If the value is 0, display the error.
szErrorMessageId	If an error occurs, return an error message ID (value). Otherwise, return four spaces.
