Eh? A file descriptor with a pending error can be considered to readable (I 
guess it depends on the driver). You should keep reading the file until read() 
returns an error (other than EAGAIN) or 0 (end-of-stream). In particular, 
POLLIN|POLLERR should only be checked together, not separately.

And stdio is no different from sockets in that respect. In fact, it can be a 
socket... The only difference is that you get to use different descriptors for 
input and output.
