typedef struct slsDetector::sharedSlsDetector slsDetector::sharedSlsDetector

Structure allocated in shared memory to store detector settings and be accessed in parallel by several applications (take care of possible conflicts!).

anonymous enum

online flags enum

See also:: setOnline

Enumerator:

GET_ONLINE_FLAG	returns wether the detector is in online or offline state
OFFLINE_FLAG	detector in offline state (i.e. no communication to the detector - using only local structure - no data acquisition possible!)
