Creating and removing directories

createDirectory :: FilePath -> FileMode -> IO () Source

createDirectory dir mode calls mkdir to create a new directory, dir, with permissions based on mode.

removeDirectory

Reading directories

data DirStream Source

openDirStream :: FilePath -> IO DirStream Source

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

readDirStream :: DirStream -> IO FilePath 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

tellDirStream :: DirStream -> IO DirStreamOffset Source

seekDirStream :: DirStream -> DirStreamOffset -> IO () Source

The working dirctory

getWorkingDirectory :: IO FilePath Source

getWorkingDirectory calls getcwd to obtain the name of the current working directory.

changeWorkingDirectory :: FilePath -> IO () Source

changeWorkingDirectory dir calls chdir to change the current working directory to dir.

changeWorkingDirectoryFd :: Fd -> IO () Source
