Abstract
A resource management system in a multimedia application programming interface for a media device such as a display controller or a sound device. Applications in a multitasking environment can request exclusive access to the resources of a media device. When an application in exclusive mode gets the focus (has control over user input to the computer), all available resources of a media device are freed for its use. The system stores the state of the media device and automatically restores the state when an application in exclusive mode regains the focus. The multimedia API provides services so that an application can restore specific media resources.
