Go Up to Using the API Guide

The API Guide is divided into two parts:

  • A task-oriented user’s guide that explains how to use API function calls to perform related database tasks, such as attaching to and detaching from a database.
  • An API function call reference that describes the purpose of each function, its syntax, its parameters, requirements, restrictions, and return values, as well as examples of use and cross-references to related functions.

The following table provides a brief description of each chapter in the API Guide:
