static const unsigned int * decode_sampleV0_2 (  QSTD *  qstd,
QSTD_sampleV0 *  sample,
const unsigned int *  dat,
unsigned char  bridge
)  [static]
 

Decodes a format 2 sample record.

Returns:
The next address to decode from
Parameters:
qstd The decoding context
sample The data structure to receive the decoded statistics
dat The statistics data
bridge The record's bridge word

static const unsigned int * decode_statsV0_diff (  QSTD *  qstd,
QSTD_statisticsV0 *  stats,
const unsigned int *  dat,
unsigned char  bridge
)  [static]
 

Decodes the statistics in difference format.

Returns:
The next address to decode from
Parameters:
qstd The decoding context
stats The data structure to receive the decoded statistics
dat The statistics data
bridge The record's bridge word

static const unsigned int * decode_statsV0_norm (  QSTD *  qstd,
QSTD_statisticsV0 *  stats,
const unsigned int *  dat,
unsigned char  bridge
)  [static]
 

Decodes a normal (not differenced) statistics record.

Returns:
The next address to decode from
Parameters:
qstd The decoding context
stats The data structure to receive the decoded statistics
dat The statistics data
bridge The record's bridge word

QSTD * QSTD_alloc (  void *  must_be_null  ) 
 

Allocates and constructs a QSTD handle.

Returns:
Pointer to the allocated handle
Parameters:
must_be_null Reserved for future use.

QSTD * QSTD_construct (  QSTD *  qstd,
void *  must_be_null
) 
 

The constructor for a QSTD control structure.

Returns:
Pointer to the QSTD control structure
Parameters:
qstd The control structure to be constructed. If NULL, a control structure will be allocated
must_be_null Reserved for future use.

const QSTD_ctx * QSTD_ctxGet (  const QSTD *  qstd  ) 
 

Locates the statistics context (meta-data).

Parameters:
qstd The statistics context

void QSTD_destruct (  QSTD *  qstd  ) 
 

The destructor for a QSTD control structure.

Returns:
Pointer to the QSS control structure
Parameters:
qstd The control structure to be destructed.

static __inline QFCP_cache * qstd_file_cache_get (  void   )  [static]
 

Returns a pointer to the file cache.

Returns:
The file cache
This routine return the handle, creating it if necessary. This not really the right architecture. This needs to be part of a QSS global environment. This can't be accomplished at this time because it would require a backwardly incompatiable change to QSSP_construct.

static __inline void qstd_sampleV0_add (  QSTD_sampleV0 *  dst,
const QSTD_sampleV0 *  src
)  [static]
 

Adds the source sample to the destination sample.

src The source sample

static __inline int qstd_sampleV0_decode (  QSTD *  qstd,
unsigned int  type_id,
unsigned char  bridge,
const unsigned int *  dat
)  [static]
 

Decodes the statistics data.

Return values:
If not negative, then the sample type (QSTD_TYPE_K)
If negative
Parameters:
qstd The QSTD context handle
type_id 0 = just the set of values 1 = the difference between the current and last set
bridge bit 0 0 = normal record; 1 = global record
dat The statistics data

int QSTD_sizeof (  void *  must_be_null  ) 
 

Returns the size, in bytes, of a QSTD control structure.

Returns:
The size, in bytes, of a QSTD control structure
Parameters:
must_be_null Parameter reserved for future use
