Performing tasks using APIs

This topic provides some examples of using APIs to perform different types of tasks.

• Examples: Packaging your own software products
  You can define, create, distribute, and maintain your own product using APIs. These examples demonstrate how you can use the APIs to package a product similar to the way IBM^® packages products.
• Examples: Retrieving a file description to a user space
  These programming examples show an application that uses a user space as a receiver variable by retrieving a file description to a user space. This approach is possible only if you use an HLL that is able to work with pointers.
• Examples: Using data queues or user queues
  Data queues and user queues both provide a means for one or more processes to communicate asynchronously. The queues can be processed FIFO (first-in first-out), LIFO (last-in first-out), or by key.
