Application programming

The z/TPFDF product provides an interface between application programs that request access to information in a database and the system software that physically accesses the stored data.

The main interfaces between application programs and the z/TPFDF product are provided through a set of C language functions and a set of assembler programming services. Assembler programming services are also referred to as macros. For examples of a typical application that uses the z/TPFDF C functions and macros, see Sample applications.

In addition, work with your database administrator to ensure that you know how the files in your database are defined. For more information about how files are defined for a z/TPFDF database, see Database administration.

The following topics provide an overview of some of the general considerations for writing application programs for the z/TPFDF product.
