Arguments
| :: Storable a | |
| => Context | |
| -> [MemFlags] | A list of |
| -> Int | The number of elements to allocate memory for. |
| -> IO (MemObject a) | The type (and there by size) of elements is determined by the result type. |
Allocates a device memory object.
Arguments
| :: Storable a | |
| => Context | |
| -> [MemFlags] | A list of |
| -> Int | The number of elements to allocate memory for. |
| -> (MemObject a -> IO b) | The function where the |
| -> IO b |
Allocates a device memory object temporarily, and makes it available for the argument function.
Arguments
| :: Storable a | |
| => CommandQueue | The |
| -> Int | The offset inside the |
| -> Int | The number of elements to read. |
| -> MemObject a | The |
| -> Ptr a | A pointer where the elements read should be stored. |
| -> IO () |
Moves the content of a memory object from device to host exposing it as C array.
Arguments
| :: Storable a | |
| => CommandQueue | |
| -> Int | The number of elements to read. |
| -> MemObject a | |
| -> IO [a] |
Moves the content of a memory object from device to host exposing it as Haskell List.
Arguments
| :: Storable a | |
| => CommandQueue | |
| -> Int | The offset inside the |
| -> Int | The number of elements to write. |
| -> Ptr a | A pointer where the elements should be read from |
| -> MemObject a | The |
| -> IO () |
Moves a host side C array to a device-side memory object
pokeListArray :: Storable a => CommandQueue -> [a] -> MemObject a -> IO ()
Moves a host side Haskell list to a device-side memory object
newListArray :: Storable a => Context -> [a] -> IO (MemObject a)
Create a memory object containing the specified list of elements.
newListArrayLen :: Storable a => Context -> [a] -> IO (MemObject a, Int)
Create a memory object containing the specified list of elements, returning the memory object together with the number of elements in the list.
enqueueCopyBuffer :: CommandQueue -> MemObject a -> MemObject a -> ClSize -> ClSize -> ClSize -> [Event] -> IO Event
memobjType :: MemObject a -> IO MemObjectType
The type of a memory object
memobjFlags :: MemObject a -> IO [MemFlags]
The flags specified when a memory object was allocated
memobjSize :: MemObject a -> IO CSize
The size of a memory object
memobjHostPtr :: MemObject a -> IO (Ptr ())
memobjMapCount :: MemObject a -> IO Int
memobjContext :: MemObject a -> IO Context
The Context this memory object is associated with.
