Functions
This section describes the functions that may be supported by derived media handler components. It is divided into the following topics:
- "Managing Your Media Handler Component" discusses the functions that allow the Movie Toolbox to manage its connection to your component.
- "General Data Management" describes the functions that allow the Movie Toolbox to manage the general characteristics of the control path through your component.
- "Graphics Data Management" tells you about the functions that allow the Movie Toolbox to manage the graphical characteristics of the control path through your component.
- "Sound Data Management" provides information about the function that allows the Movie Toolbox to manage the sound characteristics of the control path through your component.
- "Base Media Handler Utility Function" discusses a function that allows your derived media handler to report its capabilities to the base media handler.
- Note
- Many of the functions described in this chapter are optional--that is, your derived media handler may not need to support them. The description of each function discusses the issues you should consider when deciding whether or not to support a specific function.
