KMDF Callback Function Role Types for SDV

This section provides a complete list of the callback function role types that SDV supports.

Tip 

Callback function role types follow a naming convention that is similar to the convention for placeholder function names in the WDK. For example, the EVT_WDF_DEVICE_ D0_EXIT role type corresponds to the placeholder function named EvtDeviceD0Exit. To find documentation about a callback function, delete the characters "WDF" and "_" (underscore) from the role type name and then search the WDK for the resulting string. The search is case insensitive.

The following are the KMDF callback function role types for SDV:

For each role type, a driver can have only one callback function, except for the role types in Table 24-2.
