KSDISPATCH_TABLE structure

Description

The KSDISPATCH_TABLE structure contains pointers to minidriver implemented IRP dispatch routines.

Members

DeviceIoControl

Specifies the minidriver's routine to dispatch IRP_MJ_DEVICE_CONTROL IRPs to.

Read

Specifies the minidriver's routine to dispatch IRP_MJ_READ IRPs to.

Write

Specifies the minidriver's routine to dispatch IRP_MJ_WRITE IRPs to.

Flush

Specifies the minidriver's routine to dispatch IRP_MJ_FLUSH_BUFFERS IRPs to.

Close

Specifies the minidriver's routine to dispatch IRP_MJ_CLOSE IRPs to.

QuerySecurity

Specifies the minidriver's routine to dispatch IRP_MJ_QUERY_SECURITY IRPs to.

SetSecurity

Specifies the minidriver's routine to dispatch IRP_MJ_SET_SECURITY IRPs to.

FastDeviceIoControl

Specifies the minidriver's routine to dispatch fast device I/O control requests to.

FastRead

Specifies the minidriver's routine to dispatch fast read requests to.

FastWrite

Specifies the minidriver's routine to dispatch fast write requests to.

Remarks

A pointer to a dispatch table is contained in the opaque object header that is the first element of data pointed to by the file object's FsContext field.

For more information about minidriver implemented IRP dispatch routines, see KsSetMajorFunctionHandler, and DRIVER_OBJECT.
