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
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 #
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 #
