ARRAY_HANDLE aryHandle
the handle to an ARRAY type that is defined to be an input parameter to an external routine.
int *presentElts
the number of elements in the ARRAY argument that are set to a value, including NULL. An element that is a structured UDT counts as one attribute.
int lastPresentElement[]
the information for the last present element of the ARRAY value. For a 1-D ARRAY, the index to the last present element is provided as lastPresentElement[0]. If the ARRAY type is n-D, then the complete dimension information for this index is placed in cells lastPresentElement[1], lastPresentElement[2], lastPresentElement[3] ... lastPresentElement[FNC_ARRAYMAXDIMENSIONS] as needed.
