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 ACD_unpack	(	ACD_rec *	acd,
		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:

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

int ACD_unpackInit

(

ACD_rec *

acd

)

One-time initialization an ACD_rec structure.

Returns:

0, always

Parameters:

acd

The ACD_rec structure to initialize

void ACD_unpackReset

(

ACD_rec *

acd

)

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

Parameters:

acd

The ACD_rec structure to reset

unsigned int ACD_unpackSizeof

(

void

)

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

Returns:

The size, in bytes, of an ACD_rec structure

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

After allocating an ACD_rec structure, the structure should be initialized using ACD_unpackInit().
