No, C doesn't suck.  But it does seem like you guys are going through a 
lot of gyrations to do something very simple:  get a return value from a C 
program.  All you want is a number, so return one:

  int rrn;

  return (rrn);

Done.  Easy.  Every C function can return a value, including main().  All 
you need to know is, "What is the value of the last executed command?" 
The shell can find that out for you very simply.
