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.
