template<typename T >

void thrust::device_delete	(	thrust::device_ptr< T >	ptr,
		const size_t	n = `1`
	)		`[inline]`

device_delete deletes a device_ptr allocated with device_new.

Parameters:

ptr	The `device_ptr` to delete, assumed to have been allocated with `device_new`.
n	The number of objects to destroy at `ptr`. Defaults to `1` similar to `device_new`.

void thrust::device_free ( thrust::device_ptr< void > ptr ) [inline]

device_free deallocates memory allocated by the function device_malloc.

Parameters:

ptr	A `device_ptr` pointing to memory to be deallocated.

The following code snippet demonstrates how to use device_free to deallocate memory allocated by device_malloc.

  #include <thrust/device_malloc.h>
  #include <thrust/device_free.h>
  ...
  // allocate some integers with device_malloc
  const int N = 100;
  thrust::device_ptr<int> int_array = thrust::device_malloc<int>(N);

  // manipulate integers
  ...

  // deallocate with device_free
  thrust::device_free(int_array);
