Detailed Description

Interface returned to other modules which require integration with the pipeline.

To obtain this interface, the following should be performed:

pipeline_interface_t   *interface;
pipeline_interface_t   *(*get_pipeline)();

if ( ( get_pipeline = tf_find_function("pipeline_get_interface") ) != NULL ) {
    pipeline_interface = get_pipeline();
    // At this point, pipeline_interface points to the interface definition of the pipeline module
}
