type DirStream = Ptr CDir

openDirStream :: RawFilePath -> IO DirStream

openDirStream dir calls opendir to obtain a directory stream for dir.

c_opendir :: CString -> IO (Ptr CDir)

getDirectoryContentsAndAttrs :: RawFilePath -> IO [(RawFilePath, CUInt)]

data Step s o r

Constructors

Emit s o

Skip s

Stop r

Instances

Functor (Step s o)

data Stream o m r

Constructors

forall s . Stream (s -> m (Step s o r)) (m s)

streamDirectoryAndAttrs :: RawFilePath -> Stream (RawFilePath, CUInt) IO ()

sourceDirectory :: MonadSafe m => RawFilePath -> Producer (RawFilePath, CUInt) m ()

readDirStream :: DirStream -> Ptr CDirent -> IO (RawFilePath, CUInt)

readDirStream dp calls readdir to obtain the next directory entry (struct dirent) for the open directory stream dp, and returns the d_name member of that structure.

statIsDirectory :: RawFilePath -> IO Bool

statFilePath :: Bool -> Bool -> RawFilePath -> IO (Maybe FileStatus)

getStat :: Maybe Bool -> FileEntry f -> IO (Maybe (FileStatus, FileEntry f))

Get the current status for the file. If the status being requested is already cached in the entry information, simply return it from there.

d_type :: Ptr CDirent -> IO CUInt

closeDirStream :: DirStream -> IO ()

closeDirStream dp calls closedir to close the directory stream dp.
