HW_CLOCK_OBJECT structure (strmini.h)
The HW_CLOCK_OBJECT structure describes the clock associated with a stream.
Syntax
typedef struct _HW_CLOCK_OBJECT {
PHW_CLOCK_FUNCTION HwClockFunction;
ULONG ClockSupportFlags;
ULONG Reserved[2];
} HW_CLOCK_OBJECT, *PHW_CLOCK_OBJECT;
Members
HwClockFunction
Pointer to the stream's StrMiniClock routine.
ClockSupportFlags
Specifies which options the StrMiniClock routine supports.
CLOCK_SUPPORT_CAN_READ_ONBOARD_CLOCK
The StrMiniClock routine can return the current clock value for the stream's clock. The StrMiniClock routine must be able to handle a Function setting of TIME_READ_ONBOARD_CLOCK in the HW_TIME_CONTEXT structure passed as a parameter.
CLOCK_SUPPORT_CAN_RETURN_STREAM_TIME
The StrMiniClock routine can return the current presentation time stamp for the stream. The StrMiniClock routine must be able to handle a Function setting of TIME_GET_STREAM_TIME in the HW_TIME_CONTEXT structure passed as a parameter.
Reserved[2]
Reserved for system use. Do not use.
