KSDISPATCH_TABLE structure (ks.h)
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.
