Foreign.Marshal.Alloc.Calloc

The module Foreign.Marshal.Alloc.Calloc provides access to the calloc (e.g., allocated 0-initialized chunks of memory outside of the Haskell storage manager).

If any of these allocation functions fails, an exception is raised.

The storage allocated is alligned to store any basic foreign types.

Memory allocation

Initialized dynamic allocation

calloc :: Storable a => IO (Ptr a)

Allocate a block of memory that is sufficient to hold values of type a. The size of the area allocated is determined by the sizeOf method from the instance of Storable for the appropriate type. The memory is initalized to 0.

The memory may be deallocated using free or finalizerFree when no longer required.

callocBytes :: Int -> IO (Ptr a)

Allocate a block of memory of the given number of bytes. The block of memory is sufficiently aligned for any of the basic foreign tyes that fit into a memory block of the allocated size. The memory is initialized to 0.

The memory may be deallocated using free or finalizerFree when no longer required.
