KSDISPATCH_TABLE structure (ks.h)

  • Artikel

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

Syntax

typedef struct {
  PDRIVER_DISPATCH        DeviceIoControl;
  PDRIVER_DISPATCH        Read;
  PDRIVER_DISPATCH        Write;
  PDRIVER_DISPATCH        Flush;
  PDRIVER_DISPATCH        Close;
  PDRIVER_DISPATCH        QuerySecurity;
  PDRIVER_DISPATCH        SetSecurity;
  PFAST_IO_DEVICE_CONTROL FastDeviceIoControl;
  PFAST_IO_READ           FastRead;
  PFAST_IO_WRITE          FastWrite;
} KSDISPATCH_TABLE, *PKSDISPATCH_TABLE;

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.
