Detailed Description

LCB Event Buff routines.

Author:

Ed Bacho -- ebacho@slac.stanford.edu Routines to send simulated event data from the SIU to am EPU. The steps are in a loop: Read header from file with lenght of data and time Delay appropriate time according to fil Read dat into an aligned buffer Send buffer from SIU to designated EPU (on protocol=1)

Function Documentation

LCBT_installTestEvtHandler

(

)

installs simple print evt callback on protocol=1

Returns:

nothing

unsigned int * LCBT_readEvtFromFile	(	char *	fileName,
		int *	actSize32
	)

allocates memory and reads file into that buffer

Parameters:

	fileName	name of file to read
	actSize32	isnot 0, returns actual buffersize in int32

Returns:

pointer to buffer with data

References EPRINTF, and PRINTF.

void LCBT_sendEvtBuff	(	unsigned int *	evtBuff,
		int	buffSize32,
		int	latpAddr,
		int	delayNanoSec,
		int	repeat
	)

sends memory (with event data) over event fabric to EPU

Parameters:

	evtBuff	- buffer of events
	buffSize32	- length of buffer in int32's
	latpAddr	- dest address, if 0 will send to SIU0
	delayNanoSec	specify set delay between events, if 0 no delay
	repeat	repeat buffer send forever

Returns:

nothing

LCBT_uninstallTestEvtHandler

(

)

removes simple print evt callback on protocol=1

Returns:

nothing
