hANDLEToHandle :: HANDLE -> IO Handle Source #

Create a Haskell Handle from a Windows HANDLE.

Beware that this function allocates a new file descriptor. A consequence of this is that calling hANDLEToHandle on the standard Windows handles will not give you stdin, stdout, or stderr. For example, if you run this code:

import Graphics.Win32.Misc
stdoutHANDLE <- getStdHandle sTD_OUTPUT_HANDLE
stdout2 <- hANDLEToHandle stdoutHANDLE

Then although you can use stdout2 to write to standard output, it is not the case that stdout == stdout2.

withHandleToHANDLE :: Handle -> (HANDLE -> IO a) -> IO a Source #

Extract a Windows HANDLE from a Haskell Handle and perform an action on it.
