peekByteOff :: Storable a => Ptr b -> Int -> IO a

base Foreign.Storable, unliftio UnliftIO.Foreign, base-prelude BasePrelude, derive-storable Foreign.Storable.Generic Foreign.Storable.Generic.Internal, ghc-internal GHC.Internal.Foreign.Storable, rebase Rebase.Prelude

Read a value from a memory location given by a base address and offset. The following equality holds:

peekByteOff addr off = peek (addr `plusPtr` off)

PeekByteOffset :: (Int# -> ST s (DecodeAction s a)) -> DecodeAction s a

serialise Codec.Serialise.Decoding

gpeekByteOff :: GStorable a => Ptr b -> Int -> IO a

derive-storable Foreign.Storable.Generic Foreign.Storable.Generic.Internal

Read the variable from a given pointer.

gpeekByteOff :: (GStorable a, GStorableChoice a, ConstraintsPeek a) => Ptr b -> Int -> IO a

derive-storable Foreign.Storable.Generic Foreign.Storable.Generic.Internal

Read the variable from a given pointer.

chPeekByteOff :: GStorableChoice' choice a => proxy choice -> Ptr b -> Int -> IO a

derive-storable Foreign.Storable.Generic.Internal

gpeekByteOff' :: GStorable' f => [Int] -> Int -> Ptr b -> Int -> IO (f a)

derive-storable Foreign.Storable.Generic.Internal

Read the element at a given offset. Additional information about the offests of the subfields are needed.

gpeekByteOffSum' :: GStorableSum' f => Int -> Ptr b -> Int -> IO (f p)

derive-storable Foreign.Storable.Generic.Internal

Peek the type based on the tag.

internalPeekByteOff :: forall f p b . (KnownNat (NoFields f), GStorable' f) => Ptr b -> Offset -> IO (f p)

derive-storable Foreign.Storable.Generic.Internal

View the variable under a pointer, with offset.
