The following epics-related classes are not part of Epics namespace:
Class EpicsPvHeader
Public attributes:
short int iPvId // process variable ID short int iDbrType // Epics Data Type short int iNumElements // Size of PV Array
Public Member Functions:
EpicsPvHeader( short int iPvId1, short int iDbrType1, short int iNumElements1 ) :
iPvId(iPvId1), // process variable ID
iDbrType(iDbrType1), // Epics Data Type
iNumElements(iNumElements1) {} // Size of PV Array
int printPv() const;
Public Member Functions:
static void* operator new(size_t size, char* p) { return p; }
// Disable ordinary (non-placement) new: only placement new and memory mapped objects are allowed
// Disable placement delete: Not allow to delete memory mapped objects
Class EpicsPvCtrlHeader
Public attributes:
char sPvName[_iMaxPvNameLength];
Public Member Functions:
// Constructor

Pds::Epics Namespace Reference.
EPICS (Experimental Physics and Industrial Control System) is used for hardware control and readout of hardware status, values etc. These are called process variables (PV). Pdsdata contains a package that holds the epics classes needed to read the process variables from the xtc file. This is not even a complete documentation of these classes, as it would be unneccesarily detailed. Here we aim just to include the main ingredients and what the user need to know to extract the data.
The following classes, typedefs and variables are part of Epics namespace:
