Windows Driver Kit DDI reference (ns-prminterface-prm_interface)

Description

The PRM_INTERFACE structure provides a set of pointers to functions that control the operation of a PRM interface.

Members

`Version`

Specifies the version of this structure.

`UnlockModule`

A pointer to a system-defined routine to unlock a PRM module. For more information, see PRM_UNLOCK_MODULE.

`LockModule`

A pointer to a system-defined routine to lock a PRM module. For more information, see PRM_LOCK_MODULE.

`InvokeHandler`

A pointer to a system-defined routine to invoke a specific PRM handler. For more information, see PRM_INVOKE_HANDLER.

`QueryHandler`

A pointer to a system-defined routine to query for the presence of a specific PRM handler. For more information, see PRM_QUERY_HANDLER.

Remarks

All members of this structure, with the exception of Version, are pointers to functions that drivers use to perform PRM operations. Drivers obtain these pointers by calling the ExGetPrmInterface routine.
