-parameters

-param FileObject [in]

A pointer to the FILE_OBJECT structure to which a handle was returned when the clock instance was created.

-returns

This routine returns the requested time value as a value of type LONGLONG. This value is specified in 100 nanosecond units.

-remarks

You can obtain an entry point for this routine by supplying a driver-allocated KSCLOCK_FUNCTIONTABLE structure in a KSPROPERTY_CLOCK_FUNCTIONTABLE request.
