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. unsigned int len) 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 Return values: -1  The AEM contribution is not present in the event directory 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().
