Function Documentation

unsigned char * addDcm	(	QSEC_decompression **	pdcm,
		unsigned char *	next,
		unsigned int	nbits,
		const char *	name
	)			[inline, static]

Construct a decompression structure.

Constructs a decompression structure within the memory allocated for the expansion structure and returns a pointer to the location to place the next decompression

Parameters:

	pdcm	Pointer to the location to place the pointer to the decompression structure
	next	Pointer to the start of the memory to use for this decompression structure
	nbits	Number of bits in the symbols handled by this decompression structure
	name	String identifying the decompression structure

Returns:

Pointer to the location to place the next decompression structure

const unsigned int* decodeCalMeans	(	QSEC_expansion *	exp,
		const unsigned int *	buf
	)

Decompress the calorimeter log mean values.

Parameters:

	exp	Pointer to the expansion structure
	buf	Pointer to the compressed data

void QSEC_clearExpansion

(

QSEC_expansion *

exp

)

Clear away any context from a previous cycle.

Parameters:

exp

Pointer to a expansion object

QSEC_expansion* QSEC_constructExpansion	(	void *	buffer,
		unsigned	cap
	)

Construct a QSEC_expansion structure in a buffer.

Parameters:

	cap	Capacity of the decompression, maximum number of events in a single cycle
	buffer	Uninitialised memory large enough to hold the expansion structure

Returns:

Pointer to an initialised expansion structure

const unsigned int* QSEC_recoverUser	(	QSEC_expansion *	exp,
		const unsigned int *	buf
	)

Unpack the tables against which the events were encoded.

Parameters:

	buf	Pointer to the buffer where the context is held
	exp	Pointer to the structure containing the tables (an expansion)

Returns:

Pointer to the next input location to be read or NULL if there was an error during recovery of User data

void QSEC_reportExpansion	(	QSEC_expansion *	exp,
		FILE *	fp
	)

Report the contents of an expansion.

Parameters:

	exp	Pointer to a expansion object
	fp	Pointer to the destination file

void QSEC_reportExpCtx	(	QSEC_expansion *	exp,
		FILE *	fp
	)

Report the contents of the expansion context.

Parameters:

	exp	Pointer to a expansion object
	fp	Pointer to the destination file

void QSEC_setMode	(	QSEC_expansion *	exp,
		unsigned	mode
	)

Set the calibration mode of an expansion.

Parameters:

	exp	Pointer to a expansion structure
	mode	Type of calibration

size_t QSEC_sizeofExpansion

(

unsigned

cap

)

Calculate the size of the memory block required to accomodate the expansion structure.

Parameters:

cap

Capacity of the decompression, maximum number of events in a single cycle

Returns:

Size of the memory block required to accomodate the expansion structure

const unsigned int * recoverUserAcd	(	QSEC_expansion *	exp,
		const unsigned int *	buf
	)			[inline, static]

Unpack the tables against which the ACD contributions were encoded.

Parameters:
