Description

POSIX support layer for the standard libraries.

The API of this module is unstable and not meant to be consumed by the general public. If you absolutely must depend on it, make sure to use a tight upper bound, e.g., base < 4.X rather than base < 5, because the interface can change rapidly without much warning.

This library is built on *every* platform, including Win32.

Non-POSIX compliant in order to support the following features: * S_ISSOCK (no sockets in POSIX)

Synopsis

Documentation

puts :: String -> IO () Source #

data CTm Source #

type FD = CInt Source #

statGetType :: Ptr CStat -> IO IODeviceType Source #

Return a known device type or throw an exception if the device type is unknown.

statGetType_maybe :: Ptr CStat -> IO (Maybe IODeviceType) Source #

Unlike statGetType, statGetType_maybe will not throw an exception if the CStat refers to a unknown device type.

Since: base-4.20.1.0

checkForInteriorNuls :: FilePath -> CStringLen -> IO () Source #

Check an encoded FilePath for internal NUL octets as these are disallowed in POSIX filepaths. See #13660.

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.

Since: base-4.16.0.0

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

Since: base-4.16.0.0

rtsIsThreaded_ :: Int Source #

Since: base-4.16.0.0
