Sound Component-Defined Routines

This section describes the routines you need to define in order to write a sound component. You need to write routines to

load, configure, and unload your sound component
add and remove audio sources
read and set component settings
control and process audio data

Some of these routines are optional for some types of sound components. All routines return result codes. If they succeed, they should return noErr . To simplify dispatching, the Component Manager requires these routines to return a value of type ComponentResult .

See "Writing a Sound Component" for a description of how you call these routines from within a sound component. See "Sound Manager Utilities" for a description of some Sound Manager utility routines you can use in a sound component.
