makeBuffer :: Storable a => BufferTarget -> [a] -> IO BufferObjectSource
Allocate and fill a BufferObject from a list of Storables.
makeBufferLen :: Storable a => BufferTarget -> Int -> [a] -> IO BufferObjectSource
Allocate and fill a BufferObject from a list of Storables
whose length is explicitly given. This is useful when the list is
of known length, as it avoids a traversal to find the length.
fromPtr :: BufferTarget -> Int -> Ptr a -> IO BufferObjectSource
Allocate and fill a BufferObject with the given number of bytes
from the supplied pointer.
fromByteString :: BufferTarget -> ByteString -> IO BufferObjectSource
Fill a buffer with a ByteString.
fromForeignPtr :: forall a. Storable a => BufferTarget -> Int -> ForeignPtr a -> IO BufferObjectSource
Fill a buffer with data from a ForeignPtr. The application
fromForeignPtr target len fptr fills a target BufferTarget
with len elements starting from fptr.
fromVector :: forall a. Storable a => BufferTarget -> Vector a -> IO BufferObjectSource
Fill a buffer with data from a Vector.
