Unixutils-1.22: A crude interface between Haskell and Unix-like operating systems Source code Contents Index

System.Unix.SpecialDevice

Description

Construct an ADT representing block and character devices (but mostly block devices) by interpreting the contents of the Linux sysfs filesystem.

Synopsis

data SpecialDevice sysMountPoint :: FilePath ofNode :: FilePath -> IO (Maybe SpecialDevice) ofNodeStatus :: FileStatus -> Maybe SpecialDevice ofPath :: FilePath -> IO (Maybe SpecialDevice) rootPart :: IO (Maybe SpecialDevice) ofDevNo :: (DeviceID -> SpecialDevice) -> Int -> SpecialDevice ofSysName :: String -> IO (Maybe SpecialDevice) ofSysPath :: (DeviceID -> SpecialDevice) -> FilePath -> IO (Maybe SpecialDevice) toDevno :: SpecialDevice -> DeviceID ofMajorMinor :: (DeviceID -> SpecialDevice) -> Int -> Int -> SpecialDevice node :: SpecialDevice -> IO (Maybe FilePath) nodes :: SpecialDevice -> IO [FilePath] sysName :: SpecialDevice -> IO (Maybe String) splitPart :: String -> (String, Int) sysDir :: SpecialDevice -> IO (Maybe FilePath) diskOfPart :: SpecialDevice -> IO (Maybe SpecialDevice) getAllDisks :: IO [SpecialDevice] getAllPartitions :: IO [SpecialDevice] getAllCdroms :: IO [SpecialDevice] getAllRemovable :: IO [SpecialDevice]

data SpecialDevice Source

Instances Eq SpecialDevice Ord SpecialDevice Show SpecialDevice

sysMountPoint :: FilePath Source

FIXME: We should really get this value from the mount table.

ofNode :: FilePath -> IO (Maybe SpecialDevice) Source

Return the device represented by a device node, such as /dev/sda2. Returns Nothing if there is an exception trying to stat the node, or if the node turns out not to be a special device.
