Description

Synopsis

with :: (Storable α, MonadCatchIO pr) => α -> (forall s. RegionalPtr α (RegionT s pr) -> RegionT s pr β) -> pr β new :: (Storable α, MonadCatchIO pr) => α -> RegionT s pr (RegionalPtr α (RegionT s pr)) fromBool :: Num a => Bool -> a toBool :: Num a => a -> Bool copyBytes :: (ParentOf pr1 cr, ParentOf pr2 cr, MonadIO cr) => RegionalPtr α pr1 -> RegionalPtr α pr2 -> Int -> cr () moveBytes :: (ParentOf pr1 cr, ParentOf pr2 cr, MonadIO cr) => RegionalPtr α pr1 -> RegionalPtr α pr2 -> Int -> cr ()

General marshalling utilities

Combined allocation and marshalling

with :: (Storable α, MonadCatchIO pr) => α -> (forall s. RegionalPtr α (RegionT s pr) -> RegionT s pr β) -> pr β Source

new :: (Storable α, MonadCatchIO pr) => α -> RegionT s pr (RegionalPtr α (RegionT s pr)) Source

Marshalling of Boolean values (non-zero corresponds to True)

fromBool :: Num a => Bool -> a Source

Convert a Haskell Bool to its numeric representation

toBool :: Num a => a -> Bool Source

Convert a Boolean in numeric representation to a Haskell value

Marshalling of Maybe values

TODO: Define and export: maybeNew, maybeWith and maybePeek.

Marshalling lists of storable objects

TODO: Define and export: withMany.

Haskellish interface to memcpy and memmove

(argument order: destination, source)

copyBytes Source

:: (ParentOf pr1 cr, ParentOf pr2 cr, MonadIO cr) => RegionalPtr α pr1 Source -> RegionalPtr α pr2 -> Int -> cr ()

moveBytes Source

:: (ParentOf pr1 cr, ParentOf pr2 cr, MonadIO cr) => RegionalPtr α pr1 Source -> RegionalPtr α pr2 -> Int -> cr ()
