This isn't working right because data is actually a char, when you want a
char *.  See below....

That should be:  char * veri;

And then you would be getting the right value here.  I am suprised this
compiles... shouldn't the compiler complain that you are trying to convert a
char * to a char?  Maybe add -Wall to your cflags?

And then here you'd be passing in the char * and all would be well...
