setFdTimesHiRes :: Fd -> POSIXTime -> POSIXTime -> IO ()unix System.Posix.Files Like setFileTimesHiRes but uses a file descriptor instead of a path. This operation is not supported on all platforms. On these platforms, this function will raise an exception. Note: calls futimens or futimes. Support for high resolution timestamps is filesystem dependent with the following limitations:
- HFS+ volumes on OS X truncate the sub-second part of the timestamp.
setFileCreationMask :: FileMode -> IO FileModeunix System.Posix.Files setFileCreationMask mode sets the file mode creation mask to mode. Modes set by this operation are subtracted from files and directories upon creation. The previous file creation mask is returned. Note: calls umask.
setFileMode :: FilePath -> FileMode -> IO ()unix System.Posix.Files setFileMode path mode changes permission of the file given by path to mode. This operation may fail with throwErrnoPathIfMinus1_ if path doesn't exist or if the effective user ID of the current process is not that of the file's owner. Note: calls chmod.
setFileSize :: FilePath -> FileOffset -> IO ()unix System.Posix.Files Truncates the file down to the specified length. If the file was larger than the given length before this operation was performed the extra is lost. Note: calls truncate.
setFileTimes :: FilePath -> EpochTime -> EpochTime -> IO ()unix System.Posix.Files setFileTimes path atime mtime sets the access and modification times associated with file path to atime and mtime, respectively. Note: calls utime.
setFileTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()unix System.Posix.Files Like setFileTimes but timestamps can have sub-second resolution. Note: calls utimensat or utimes. Support for high resolution timestamps is filesystem dependent with the following limitations:
- HFS+ volumes on OS X truncate the sub-second part of the timestamp.
-
unix System.Posix.Files Set group ID on execution.
setOwnerAndGroup :: FilePath -> UserID -> GroupID -> IO ()unix System.Posix.Files setOwnerAndGroup path uid gid changes the owner and group of path to uid and gid, respectively. If uid or gid is specified as -1, then that ID is not changed. Note: calls chown.
setSymbolicLinkOwnerAndGroup :: FilePath -> UserID -> GroupID -> IO ()unix System.Posix.Files Acts as setOwnerAndGroup but does not follow symlinks (and thus changes permissions on the link itself). Note: calls lchown.
setSymbolicLinkTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()unix System.Posix.Files Like setFileTimesHiRes but does not follow symbolic links. This operation is not supported on all platforms. On these platforms, this function will raise an exception. Note: calls utimensat or lutimes. Support for high resolution timestamps is filesystem dependent with the following limitations:
- HFS+ volumes on OS X truncate the sub-second part of the timestamp.
