 So, foo() function could be called several times that the memory will be
freed when the program terminates !?

 Conclusion: it's only needed to free() memory when the function doesn't 
return the memory allocation !?

example:

int foo()
{
  int a ;
  char *b ;

  b = malloc(3*sizeof(char)) ;
  .
  . . .
  .
  free(b) ;

  a = 2 ;
  return a ;
}

 Only in this cases it will be needed to free() memory !?

 Thanks.
