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 :: FilePath -> IO () | Source

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
