sUBLANGID :: LANGID -> SubLANGID Source

newForeignHANDLE :: HANDLE -> IO ForeignHANDLE Source

handleToWord :: HANDLE -> UINT_PTR Source

nullHANDLE :: HANDLE Source

nullHINSTANCE :: HINSTANCE Source

nullFinalHANDLE :: ForeignPtr a Source

iNVALID_HANDLE_VALUE :: HANDLE Source

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.

withStablePtr :: a -> (StablePtr a -> IO b) -> IO b Source

failIf :: (a -> Bool) -> String -> IO a -> IO a Source

failIf_ :: (a -> Bool) -> String -> IO a -> IO () Source

failIfZero :: (Eq a, Num a) => String -> IO a -> IO a Source

failIfFalse_ :: String -> IO Bool -> IO () Source

failUnlessSuccess :: String -> IO ErrCode -> IO () Source

failUnlessSuccessOr :: ErrCode -> String -> IO ErrCode -> IO Bool Source

eRROR_INSUFFICIENT_BUFFER :: ErrCode Source

eRROR_MOD_NOT_FOUND :: ErrCode Source

eRROR_PROC_NOT_FOUND :: ErrCode Source

errorWin :: String -> IO a Source

failWith :: String -> ErrCode -> IO a Source

ddwordToDwords :: DDWORD -> (DWORD, DWORD) Source

dwordsToDdword :: (DWORD, DWORD) -> DDWORD Source

try :: String -> (LPTSTR -> UINT -> IO UINT) -> UINT -> IO String Source

nullPtr :: Ptr a Source

The constant nullPtr contains a distinguished value of Ptr that is not associated with a valid memory location.
