Don't want to step on any toes here, but there are a couple of syntactic
errors in this code fragment (marked below).  Haven't tried the code, 
so I can't say anything about the logic (which looks ok). :)

Should be lowercase:
          fd_set rfds;

Could check for error return here, but not too likely.

Leave off the first paren:
          return FD_ISSET(0, &rfds);

Just in case robert isn't an experienced programmer. :)
