Hi! I’m new on this list, and right now I’m wondering something… Does  
somedy know if Ruby streams are Unix File Descriptor’s compatible? I  
need to use a file descriptor opened by another process (a daemon  
written in C). I’m reading about the IO class, it seems to have a method  
that allows creating an IO object using a file descriptor (an integer)  
as a parameter. But I see that File has something similar (I guess that  
Files is a subcclass of IO). I’m new at Ruby, so I’m not sure about its  
internals.  
Does somebody know something about this? Thanks.
