Synopsis

Documentation

puts :: String -> IO () Source #

data CTm Source #

type FD = CInt Source #

setEcho :: FD -> Bool -> IO () Source #

setCooked :: FD -> Bool -> IO () Source #

tcSetAttr :: FD -> (Ptr CTermios -> IO a) -> IO a Source #

c_interruptible_open :: CFilePath -> CInt -> CMode -> IO CInt Source #

The same as c_safe_open, but an interruptible operation as described in Control.Exception—it respects uninterruptibleMask but not mask.

We want to be able to interrupt an openFile call if it's expensive (NFS, FUSE, etc.), and we especially need to be able to interrupt a blocking open call. See #17912.

Since: base-4.16.0.0

hostIsThreaded :: Bool Source #

Consult the RTS to find whether it is threaded.
