Description
POSIX support layer for the standard libraries. 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)

Documentation
data CSigaction Source #
statGetType :: Ptr CStat -> IO IODeviceType Source #
peekFilePathLen :: CStringLen -> IO FilePath Source #
checkForInteriorNuls :: FilePath -> CStringLen -> IO () Source #
Check an encoded FilePath for internal NUL octets as these are
disallowed in POSIX filepaths. See #13660.
throwInternalNulError :: FilePath -> IO a Source #
setCloseOnExec :: FD -> IO () 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.

hostIsThreaded :: Bool Source #
Consult the RTS to find whether it is threaded.
