|Alas, GHC provides no function to read from Fd to an allocated buffer.
The library function fdRead is not appropriate as it returns a string
already. I'd rather get data from a buffer.
Furthermore, fdRead (at least in GHC) allocates a new buffer each
time it is called. This is a waste. Yet another problem with fdRead
is in raising an exception on any IOError or even EOF. I'd rather
avoid exceptions altogether.
|The following fseek procedure throws no exceptions.
|Haskell representation for errno values.
The implementation is deliberately exposed, to allow users to add
their own definitions of Errno values.
|poll if file descriptors have something to read
Return the list of read-pending descriptors
