Hi there,
  
I meet a problem when I try to get a character from keyboard in a subprocess 
and end the 
subprocess; I use gets or getc to read it,  
part of code is as below: 
fork{f=STDIN.getc 
if f==101 then  
........ 
end 
.... 
... 
}
 
but I always get an error message: ERRNO:EIO. anyond can tell me what's wrong 
with my 
code? And how to fix it? Or where I can find the description of error? Thanks,
 
Maggie
