type BOOL = Bool Source #

type INT = Int32 Source #

type ATOM = UINT Source #

type Addr = Ptr () Source #

type LPVOID = Ptr () Source #

maybeNum :: Num a => Maybe a -> a Source #

numToMaybe :: (Eq a, Num a) => a -> Maybe a Source #

withTString :: String -> (LPTSTR -> IO a) -> IO a Source #

withTStringLen :: String -> ((LPTSTR, Int) -> IO a) -> IO a Source #

type HANDLE = Ptr () Source #

type HINSTANCE = Ptr () Source #

type HMODULE = Ptr () Source #

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

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

failIfNull :: String -> IO (Ptr a) -> IO (Ptr a) Source #

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

localFree :: Ptr a -> IO (Ptr a) Source #

nullPtr :: Ptr a Source #

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