Function Documentation

begin_of_run()

INT begin_of_run	(	INT	run_number,
		char *	error
	)

Begin of Run.

Called every run start transition. Set equipment status in ODB, start acquisition on the modules.

Parameters

[in]	run_number	Number of the run being started
[out]	error	Can be used to write a message string to midas.log

Definition at line 118 of file largefe.cxx.

{
   return SUCCESS;
}

end_of_run()

INT end_of_run	(	INT	run_number,
		char *	error
	)

End of Run.

Called every stop run transition. Set equipment status in ODB, stop acquisition on the modules.

Parameters

[in]	run_number	Number of the run being ended
[out]	error	Can be used to write a message string to midas.log

Definition at line 125 of file largefe.cxx.

{
   return SUCCESS;
}

frontend_exit()

INT frontend_exit

(

void

)

Frontend exit.

Runs at frontend shutdown. Disconnect hardware and set equipment status in ODB

Returns

Midas status code

Definition at line 111 of file largefe.cxx.

{
   return SUCCESS;
}

frontend_init()

INT frontend_init

(

void

)

Frontend initialization.

Runs once at application startup. We initialize the hardware and optical interfaces and set the equipment status in ODB. We also lock the frontend to once physical cpu core.

Returns

Midas status code

Definition at line 104 of file largefe.cxx.

{
   return SUCCESS;
}

frontend_loop()

INT frontend_loop

(

void

)

Frontend loop.

If frontend_call_loop is true, this routine gets called when the frontend is idle or once between every event.

Returns

Midas status code

Definition at line 145 of file largefe.cxx.

{
   return SUCCESS;
}

interrupt_configure()

INT interrupt_configure	(	INT	cmd,
		INT	source,
		PTYPE	adr

   case CMD_INTERRUPT_DETACH:
      break;
   }
   return SUCCESS;
}

pause_run()

INT pause_run	(	INT	run_number,
		char *	error
	)

Pause Run.

Called every pause run transition.

Parameters

[in]	run_number	Number of the run being ended
[out]	error	Can be used to write a message string to midas.log

Returns

Midas status code

Definition at line 132 of file largefe.cxx.

   /* Example for camac
   int i;
   DWORD lam;
 
   for (i = 0; i < count; i++) {
      cam_lam_read(LAM_SOURCE_CRATE(source), &lam);
 
      if (lam & LAM_SOURCE_STATION(source))
         if (!test)
            return lam;
   }
   */
 
   return 0;
}

read_large_event()

INT read_large_event	(	char *	pevent,
		INT	off
	)

Definition at line 201 of file largefe.cxx.

{
   DWORD *pddata;
 
   /* init bank structure */
   bk_init32(pevent);
 
   bk_create(pevent, "BIGG", TID_DWORD, (void **) &pddata);
   memset((char *) pddata, 0x0000, 100);
   pddata += 1000000;
   memset((char *) pddata - 100, 0xFFFF, 100);
   bk_close(pevent, pddata);
 
   return bk_size(pevent);
