Functions
int	dataCallback (detectorData *pData, int iframe, int isubframe, void *pArg)
int	main (int argc, char **argv)

Detailed Description

This file is an example of how to implement the slsDetectorUsers class You can compile it linking it to the slsDetector library

g++ mainClient.cpp -L lib -lSlsDetector -L/usr/lib64/ -L lib2 -lzmq -pthread -lrt -lm -lstdc++

where,

lib is the location of libSlsDetector.so

lib2 is the location of the libzmq.a. [ libzmq.a is required only when using data call backs and enabling data streaming from receiver to client. It is linked in manual/manual-api from slsReceiverSoftware/include ]

Definition in file mainClient.cpp.

Function Documentation

int dataCallback	(	detectorData *	pData,
		int	iframe,
		int	isubframe,
		void *	pArg
	)

Data Call back function defined

Parameters

pData	pointer to data structure received from the call back
iframe	frame number of data passed
isubframe	sub frame number of data passed ( only valid for EIGER in 32 bit mode)

Example of a main program using the slsDetectorUsers class

• Arguments are optional
  • argv[1] : Configuration File
  • argv[2] : Measurement Setup File
  • argv[3] : Detector Id (default is zero)

• if specified, set ID from argv[3]
• slsDetectorUsers Object is instantiated with appropriate ID
• if specified, load configuration file (necessary at least the first time it is called to properly configure advanced settings in the shared memory)
• set detector in shared memory online (in case no config file was used)
• set receiver in shared memory online (in case no config file was used)
• registering data callback
• ensuring detector status is idle before starting acquisition. exiting if not idle
• if provided, load detector settings
• start measurement
• returning when acquisition is finished or data are avilable
• delete slsDetectorUsers object
