The Toolkit provides a sample captioning system to assist application programmers in adding captioning to multimedia applications. The sample captioning system consists of three parts: the Caption Creation Utility program, Caption DLL, and Caption Sample Application. The Caption Creation Utility program (located in \TOOLKIT\SAMPLES\MM\CAPTION subdirectory) creates a "caption" file. This is a text file containing timing information relating to its associated audio file. The Caption DLL (located in the \TOOLKIT\SAMPLES\MM\CAPDLL directory) provides functions that drive the display and management of the caption file in a "caption window" in a PM application. The Caption Sample Application (located in the \TOOLKIT\SAMPLES\MM\CAPSAMP subdirectory) demonstrates how an application uses the functions provided by the Caption DLL to take advantage of its services. As with all OS/2 multimedia samples, the source code is provided for all three components. You can use the three components as provided or modify them to meet specific requirements. See Sample Application Programs for more information on the captioning components.
