data Arg

newtype Arg
libffi Foreign.LibFFI.Base
Arg :: (forall a . (Ptr CType -> Ptr CValue -> IO a) -> IO a) -> Arg
libffi Foreign.LibFFI.Base
argByteString :: ByteString -> Arg
libffi Foreign.LibFFI.Types
Like argString, but for ByteString's.
argCChar :: CChar -> Arg
libffi Foreign.LibFFI.Types
argCDouble :: CDouble -> Arg
libffi Foreign.LibFFI.Types
argCFloat :: CFloat -> Arg
libffi Foreign.LibFFI.Types
argCInt :: CInt -> Arg
libffi Foreign.LibFFI.Types
argCLong :: CLong -> Arg
libffi Foreign.LibFFI.Types
argCSize :: CSize -> Arg
libffi Foreign.LibFFI.Types
argCTime :: CTime -> Arg
libffi Foreign.LibFFI.Types
argCUChar :: CUChar -> Arg
libffi Foreign.LibFFI.Types
argCUInt :: CUInt -> Arg
libffi Foreign.LibFFI.Types
argCULong :: CULong -> Arg
libffi Foreign.LibFFI.Types
argCWchar :: CWchar -> Arg
libffi Foreign.LibFFI.Types
argConstByteString :: ByteString -> Arg
libffi Foreign.LibFFI.Types
Like argByteString, but changing the string from C breaks referential transparency.
argFunPtr :: FunPtr a -> Arg
libffi Foreign.LibFFI.Types
argInt16 :: Int16 -> Arg
libffi Foreign.LibFFI.Types
argInt32 :: Int32 -> Arg
libffi Foreign.LibFFI.Types
argInt64 :: Int64 -> Arg
libffi Foreign.LibFFI.Types
argInt8 :: Int8 -> Arg
libffi Foreign.LibFFI.Types
Note that on e.g. x86_64, Int /= CInt
argPtr :: Ptr a -> Arg
libffi Foreign.LibFFI.Types
argString :: String -> Arg
libffi Foreign.LibFFI.Types
The string argument is passed to C as a char * pointer, which is freed afterwards. The argument should not contain zero-bytes.

argWord32 :: Word32 -> Arg
