The Message Queue Interface overview

The Message Queue Interface consists of the following:

• Calls through which programs can access the queue manager and its facilities
• Structures that programs use to pass data to, and get data from, the queue manager
• Elementary data types for passing data to, and getting data from, the queue manager

• Calls through which WebSphere MQ for Windows and WebSphere MQ on UNIX and Linux systems programs can commit and back out changes.
• Include files that define the values of constants supplied on these platforms.
• Library files to link your applications.
• A suite of sample programs that demonstrate how to use the MQI on these platforms. For further information about these samples, see Sample programs for distributed platforms.
• Sample source and executable code for bindings to external transaction managers.
