KSCLOCK_FUNCTIONTABLE structure (ks.h)

The KSCLOCK_FUNCTIONTABLE structure describes a function table for the master clock.

Syntax

typedef struct {
  PFNKSCLOCK_GETTIME        GetTime;
  PFNKSCLOCK_GETTIME        GetPhysicalTime;
  PFNKSCLOCK_CORRELATEDTIME GetCorrelatedTime;
  PFNKSCLOCK_CORRELATEDTIME GetCorrelatedPhysicalTime;
} KSCLOCK_FUNCTIONTABLE, *PKSCLOCK_FUNCTIONTABLE;

Members

GetTime

Pointer to a driver-allocated KStrClockGetTime routine.

GetPhysicalTime

Pointer to a driver-allocated KStrClockGetPhysicalTime routine.

GetCorrelatedTime

Pointer to a driver-allocated KStrClockGetCorrelatedTime routine.

GetCorrelatedPhysicalTime

Pointer to a driver-allocated KStrClockGetCorrelatedPhysicalTime routine.

Remarks

Supply this structure in a KSPROPERTY_CLOCK_FUNCTIONTABLE request. The property request then returns pointers to the requested routines.

The function pointers returned in this structure are valid until the clock's file object is released.
