Define Documentation

#define HW_ACCESS	(	_hwa,
		_idx		)	_hwa[_idx];

Addresses the ACD half-word array in a way that is compatiable with big or little endian machines.

Returns:

Value at the halfword index

Parameters:

	_hwa	The halfword array to be accessed
	_idx	The value to be transformed

Function Documentation

int QSE_aemUnpack	(	QSE_aem *	aem,
		const EBF_dir *	dir
	)

Unpacks an ACD record from the AEM into a standard structure.

Returns:

Status. This is a bit mask of the enumeration QSE_AEM_STATUS_M. In general, negative values are failures and positive values are successes, but with possible qualifications.

Parameters:

	aem	Pointer to the data structure to receive the unpacked data
	dir	The EBF directory

int QSE_aemUnpackDat	(	QSE_aem *	aem,
		const void *	dat,
		unsigned int	len
	)

Unpacks an ACD record from the AEM into a standard structure.

Returns:

Status. The only failure is if more than 18 PHAs are found to be present on an given FREE board or the serial decode extends beyond the maxwrds

Parameters:

	aem	Pointer to the data structure to receive the unpacked data
	dat	The AEM data for this event
	len	The length of the data in bytes

int QSE_aemUnpackInit

(

QSE_aem *

aem

)

One-time initialization an QSE_aem structure.

Returns:

0, always

Parameters:

aem

The QSE_aem structure to initialize

void QSE_aemUnpackReset

(

QSE_aem *

aem

)

Resets the QSE_aem structure, preparing it for a new event.

Parameters:

aem

The QSE_ame structure to reset

unsigned int QSE_aemUnpackSizeof

(

void

)

Returns the size, in bytes, of an QSE_aem structure.

Returns:

The size, in bytes, of an ACD_rec structure

This function should be called to determine the size of an QSE_aem structure. This allows the calling program to avoid including the structure definition an QSE_aem.

After allocating an QSE_aem structure, the structure should be initialized using QSE_aemUnpackInit().
