Fields

• fuseGetFileStat :: FilePath -> IO (Either Errno FileStat)

  Implements getSymbolicLinkStatus operation (POSIX lstat(2)).

• fuseReadSymbolicLink :: FilePath -> IO (Either Errno FilePath)

  Implements readSymbolicLink operation (POSIX readlink(2)). The returned FilePath might be truncated depending on caller buffer size.

• fuseCreateDevice :: FilePath -> EntryType -> FileMode -> DeviceID -> IO Errno

  Implements createDevice (POSIX mknod(2)). This function will also be called for regular file creation.

• fuseCreateDirectory :: FilePath -> FileMode -> IO Errno

  Implements createDirectory (POSIX mkdir(2)).

• fuseRemoveLink :: FilePath -> IO Errno

  Implements removeLink (POSIX unlink(2)).

• fuseRemoveDirectory :: FilePath -> IO Errno

  Implements removeDirectory (POSIX rmdir(2)).

• fuseCreateSymbolicLink :: FilePath -> FilePath -> IO Errno

  Implements createSymbolicLink (POSIX symlink(2)).

• fuseRename :: FilePath -> FilePath -> IO Errno

  Implements rename (POSIX rename(2)).

• fuseCreateLink :: FilePath -> FilePath -> IO Errno

  Implements createLink (POSIX link(2)).

• fuseSetFileMode :: FilePath -> FileMode -> IO Errno

  Implements setFileMode (POSIX chmod(2)).

• fuseSetOwnerAndGroup :: FilePath -> UserID -> GroupID -> IO Errno

  Implements setOwnerAndGroup (POSIX chown(2)).

• fuseSetFileSize :: FilePath -> FileOffset -> IO Errno

  Implements setFileSize (POSIX truncate(2)).

• fuseSetFileTimes :: FilePath -> EpochTime -> EpochTime -> IO Errno

  Implements setFileTimes (POSIX utime(2)).

• fuseOpen :: FilePath -> OpenMode -> OpenFileFlags -> IO (Either Errno fh)

  Implements openFd (POSIX open(2)). On success, returns Right of a filehandle-like value that will be passed to future file operations; on failure, returns Left of the appropriate Errno.

  No creation, exclusive access or truncating flags will be passed. This should check that the operation is permitted for the given flags.

• fuseRead :: FilePath -> fh -> ByteCount -> FileOffset -> IO (Either Errno ByteString)

  Implements Unix98 pread(2). It differs from fdRead by the explicit FileOffset argument. The fuse.h documentation stipulates that this "should return exactly the number of bytes requested except on EOF or error, otherwise the rest of the data will be substituted with zeroes."

• fuseWrite :: FilePath -> fh -> ByteString -> FileOffset -> IO (Either Errno ByteCount)

  Implements Unix98 pwrite(2). It differs from fdWrite by the explicit FileOffset argument.

• fuseGetFileSystemStats :: String -> IO (Either Errno FileSystemStats)

  Implements statfs(2).

• fuseFlush :: FilePath -> fh -> IO Errno

  Called when close(2) has been called on an open file. Note: this does not mean that the file is released. This function may be called more than once for each open(2). The return value is passed on to the close(2) system call.

• fuseRelease :: FilePath -> fh -> IO ()

  Called when an open file has all file descriptors closed and all memory mappings unmapped. For every open call there will be exactly one release call with the same flags. It is possible to have a file opened more than once, in which case only the last release will mean that no more reads or writes will happen on the file.

• fuseSynchronizeFile :: FilePath -> SyncType -> IO Errno

  Implements fsync(2).

• fuseOpenDirectory :: FilePath -> IO Errno

  Implements opendir(3). This method should check if the open operation is permitted for this directory.

• fuseReadDirectory :: FilePath -> IO (Either Errno [(FilePath, FileStat)])

  Implements readdir(3). The entire contents of the directory should be returned as a list of tuples (corresponding to the first mode of operation documented in fuse.h).

• fuseReleaseDirectory :: FilePath -> IO Errno

  Implements closedir(3).

• fuseSynchronizeDirectory :: FilePath -> SyncType -> IO Errno

  Synchronize the directory's contents; analogous to fuseSynchronizeFile.

• fuseAccess :: FilePath -> Int -> IO Errno

  Check file access permissions; this will be called for the access() system call. If the default_permissions mount option is given, this method is not called. This method is also not called under Linux kernel versions 2.4.x

• fuseInit :: IO ()

  Initializes the filesystem. This is called before all other operations.

• fuseDestroy :: IO ()

  Called on filesystem exit to allow cleanup.
