I know nothing about signals, but this program when run inside bash does not 
seem to run callback() *ever*.
^c does not run it. Closing the bash window does not run it. But if you 
remove the loop then it *is* run.

#include <stdio.h>
void callback()
{
  FILE *current;

 current=fopen("test.txt","a");
 fprintf(current,"atexit");
}

int main()
{
  atexit(*callback);
  while(1)
  {};
}
