Now we make the routines into commands

#ifndef __P_EX2_H__

#define __P_EX2_H__

#include <Event.h>

int process_event (Event *e); //++CINT

void h1enable(); //++CINT

void h1disable(); //++CINT

void h2enable(); //++CINT

void h2disable(); //++CINT

void h1status(); //++CINT

void h2status(); //++CINT

#endif /* __P_EX2_H__ */

With the “//++CINT tag we make the routines visible to cint and can call them from the command prompt, setting the global variables accordingly.

Type ? for help. Commands must be C++ statements.

Enclose multiple statements between { }.

root [0] gSystem->Load("libp_ex2.so");

root [1] h1enable();

root [2] h1disable();

root [3] h1status();

H1 is disabled

root [4] h1enable();

root [5] h1status();

H1 is enabled

root [6] h2status();

H2 is enabled

root [7] h2disable();

root [8] h2status();

H2 is disabled

root [9]

We can also use routines which take parameters, anything, so this is a very versatile tool to steer and configure our analysis.
