KsDispatchQuerySecurity function

Description

The KsDispatchQuerySecurity function is used in the KSDISPATCH_TABLE.QuerySecurity entry to handle querying about the current security descriptor. The assumption is that the KSOBJECT_HEADER structure is being used in the FsContext data structure and that the CreateItem points to a valid item that optionally contains a security descriptor.

Parameters

`DeviceObject` [in]

Specifies the device object associated with the IRP.

`Irp` [in]

Specifies the IRP that is being handled.

Return value

The KsDispatchQuerySecurity function returns the security query status and completes the IRP if a security descriptor is present. If no security descriptor is present, it returns STATUS_NO_SECURITY_ON_OBJECT.
