Parameters - Access Module

The Teradata Access Module interface is supported by two parameters; there are no other elements or global or environmental variables. Each parameter is a structure pointer, and the structures provide the communication between an Access Module and a Teradata utility:

The first parameter specifies a general, function‑independent structure that contains the common fields required for all Access Module functions.

The second parameter specifies a function‑dependent structure that contains the unique fields required for a specific Access Module function:

File Close

File Get Position

File Open

File Read

File Set Position

File Write

Get Attribute

Identification

Initialization

Put Attribute

Shutdown

The second parameter is passed as a void.

Chapter 3 provides a detailed description of each Access Module function, as well as an explanation of the corresponding function‑dependent structure.
