System.Posix.Handle

This module provides versions of functions from System.Posix.Files that operate on Handle instead of FilePath or Fd. This is useful to prevent race conditions that may arise from looking up the same path twice.

Documentation

hSetMode :: Handle -> FileMode -> IO ()

hSetMode h mode acts like setFileMode or setFdMode on a Handle.

Note: calls fchmod.

hGetStatus :: Handle -> IO FileStatus

hGetStatus h acts like getFileStatus or getFdStatus on a Handle.

Note: calls fstat.

hSetOwnerAndGroup :: Handle -> UserID -> GroupID -> IO ()

hSetOwnerAndGroup h uid gid acts like setOwnerAndGroup or setFdOwnerAndGroup on a Handle.

Note: calls fchown.

hSetSize :: Handle -> FileOffset -> IO ()

hSetSize h size acts like setFileSize or setFdSize on a Handle. It is equivalent to hSetFileSize but is provided here for completeness.

hGetPathVar :: PathVar -> Handle -> IO Limit

hGetPathVar var h acts like getPathVar or getFdPathVar on a Handle.

Note: calls fpathconf.
