Events are tagged with a sequence numberin the order they occur on the target. When displayed in WindView, theyare spaced equidistantly along the timeline.INCLUDE FILES:SEE ALSO:NOMANUAL*/#include "vxWorks.h"#include "private/seqDrvP.h"/* locals */static int sequence; /* a static variable used to hold the sequence *//********************************************************************************* seqStamp - implements a sequencer.** NOMANUAL*/UINT32 seqStamp (void)    {    sequence++;    return (sequence);    }/********************************************************************************* seqStampLock - implements a sequencer.** NOMANUAL*/UINT32 seqStampLock (void)    {    sequence++;    return (sequence);    }/********************************************************************************* seqEnable - Enable the sequencer** NOMANUAL*/STATUS seqEnable (void)    {    sequence = 0;    return (OK);    }/********************************************************************************* seqDisable - disable the sequencer** NOMANUAL*/STATUS seqDisable (void)    {    return (OK);    }/********************************************************************************* seqConnect - connect to a sequencer.** NOMANUAL*/STATUS seqConnect     (    FUNCPTR dummy,    int dummyArg    )    {    return (OK);    }/********************************************************************************* seqPeriod - period of sequencer.** NOMANUAL*/UINT32 seqPeriod (void)    {    return (0xffffffff);    }/********************************************************************************* seqFreq - frequency of sequencer** NOMANUAL*/UINT32 seqFreq (void)    {    return (1);    }
