Function Documentation

void EMP_hdrClear

(

EMP_hdr *

hdr

)

Clear the LSF_statsHdr structure.

Parameters:

hdr

Pointer to LSF_statsHdr structure to fill in

Referenced by initMsg(), and output().

unsigned int EMP_hdrEvtSet	(	EMP_hdrEvt *	evt,
		unsigned int	relative,
		unsigned long long	seq,
		unsigned int	gemClock,
		unsigned int	gemStrobe
	)

Sets specified event marker.

Returns:

status

Parameters:

	evt	Pointer to the target EMP_hdrEvt
	relative	The relative (to the beginning of the buffer) event number (1 = first event)
	seq	Extended seqence number of the event
	gemClock	Event clock register read from GEM contributor of event
	gemStrobe	Event PPS cock register read from GEM contributor of event

This is convenient routine to fill in event info that is stored in a EMP_emp structure within an LSF packet for eventual output as science data on the SSR.

void EMP_timetones_get_set

(

EMP_timetones_get_rtn

rtn

)

Routine to set the routine to get the timetone information.

Parameters:

rtn

The timetone get routine
