Comment(by duncan):
See `GHC/IO/FD.hs`, in the "FD operations" section, in the `!
mingw32_HOST_OS` case:
{{{
readRawBufferPtrNoBlock :: String -> FD -> Ptr Word8 -> Int -> CSize -> IO
CInt
readRawBufferPtrNoBlock = readRawBufferPtr
writeRawBufferPtrNoBlock :: String -> FD -> Ptr Word8 -> Int -> CSize ->
IO CInt
writeRawBufferPtrNoBlock = writeRawBufferPtr
}}}
There does not seem to be any non-blocking impl here for windows (where
there is one for unix just above).
