This chapter describes the entry points that are exported by the dynamic link library of a presentation driver: 

 EXPORTS
    OS2_PM_DRV_RING_LEVELS      /* All drivers - Optional  */
    OS2_PM_DRV_ENABLE_LEVELS    /* All drivers - Optional  */
    OS2_PM_DRV_ENABLE           /* All drivers - Mandatory */

The functions in this chapter are listed in the following index table. A detailed description of each function follows the table.
