GHC.RTS.Flags.Experimental
Description
The API of this module is unstable and is coupled to GHC's internals. As such if you depend on it, you should expect to follow GHC's releases. This API could change without warning.
Descriptions of flags can be seen in
GHC User's Guide,
or by running RTS help message using +RTS --help.

data IoSubSystem Source #
The I/O SubSystem to use in the program.
Since: base-4.9.0.0
Constructors
| IoPOSIX | Use a POSIX I/O Sub-System |
| IoNative | Use platform native Sub-System. For unix OSes this is the same as IoPOSIX, but on Windows this means use the Windows native APIs for I/O, including IOCP and RIO. |
