Creating and removing directories
createDirectory :: RawFilePath -> FileMode -> IO () Source
createDirectory dir mode calls mkdir to
create a new directory, dir, with permissions based on
mode.
removeDirectory :: RawFilePath -> IO () Source
Reading directories
openDirStream :: RawFilePath -> IO DirStream Source
openDirStream dir calls opendir to obtain a
directory stream for dir.
readDirStream :: DirStream -> IO RawFilePath Source
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.
rewindDirStream :: DirStream -> IO () Source
rewindDirStream dp calls rewinddir to reposition
the directory stream dp at the beginning of the directory.
closeDirStream :: DirStream -> IO () Source
closeDirStream dp calls closedir to close
the directory stream dp.
data DirStreamOffset Source
seekDirStream :: DirStream -> DirStreamOffset -> IO () Source
The working dirctory
getWorkingDirectory :: IO RawFilePath Source
getWorkingDirectory calls getcwd to obtain the name
of the current working directory.
changeWorkingDirectory :: RawFilePath -> IO () Source
changeWorkingDirectory dir calls chdir to change
the current working directory to dir.
changeWorkingDirectoryFd :: Fd -> IO () Source
