Typedef Documentation

EDSD_sizesSummary

Typedef for struct _EDSD_sizesSummary.

Holds the summary information of the sizes of a collection of events.

EDSD_sizeTem

Typedef for struct EDSD_sizesTem.

Note that because of LCB padding the total size of the TEM record is not necessarily the sum of the TKR and CAL contributions.

Function Documentation

static void calcSizesSummary	(	EDSD_sizesSummary *	summary,
		const EDSD_size *	sizes,
		int	count
	)			[static]

Calculates the size summary record.

Parameters:

	summary	The summary record to fill in
	sizes	The vector of sizes
	count	The number of sizes vectors

int EDSD_sizesConstruct	(	EDSD_sizesCtl *	ctl,
		unsigned int	nevts
	)

Allocates and initializes the unpacking buffers.

Returns:

Status

Parameters:

	ctl	Pointer to the control buffer
	nevts	The number of events to process

int EDSD_sizesDestruct

(

EDSD_sizesCtl *

ctl

)

DeAllocates and the sizes control structure.

Returns:

Status

Parameters:

ctl

Pointer to the control buffer

unsigned int EDSD_sizesProcess	(	EDSD_sizesCtl *	ctl,
		unsigned int	pktBytes,
		EBF_pkt *	pkt,
		EBF_siv	siv,
		EDS_fwIxb *	ixb
	)

Evaluates the sizes of the various pieces of the event.

Returns:

The EDSD_fw fate and needs status

Parameters:

	ctl	The control/context parameter
	pktBytes	The number of bytes in pkt, includes the packet header
	pkt	The event data packet
	siv	The packet's state information vector
	ixb	The framework's information exchange block

This piece of code analyses the sizes of the various contributions to the event. This is only called back on the last packet of an event.

void EDSD_sizesReport

(

const EDSD_sizesCtl *

ctl

)

Reports the results.

Parameters:

ctl

The control parameter

int EDSD_sizesSizeof

(

void

)

Returns the size, in bytes, of the EDSD sizes control block.

Returns:

The size, in bytes, of the EDSD sizes control block

static void printSizesSummary

(

const EDSD_sizesSummary *

summary

)

[static]

Prints the average sizes of the various event contributors.

Parameters:

summary

Structure containing the various accumulated sizes
