## Class template local_buffer

boost::compute::local_buffer — Represents a local memory buffer on the device.

## Synopsis

    // In header: <boost/compute/memory/local_buffer.hpp>

    template<typename T>
    class local_buffer {
    public:

      // public member functions
      local_buffer(const size_t);
      local_buffer(const local_buffer &);
      local_buffer & operator=(const local_buffer &);
      ~local_buffer();
      size_t size() const;
    };

## Description

The local_buffer class represents a block of local memory on a compute device.

This class is most commonly used to set local memory arguments for compute kernels:

    // set argument to a local buffer with storage for 32 float's
    kernel.set_arg(0, local_buffer<float>(32));

### `local_buffer` public member functions

1.     local_buffer(const size_t size);

   Creates a local buffer object for `size` elements.

2.     local_buffer(const local_buffer & other);

   Creates a local buffer object as a copy of `other`.

3.     local_buffer & operator=(const local_buffer & other);

   Copies `other` to `*this`.

4.     ~local_buffer();

   Destroys the local memory object.

5.     size_t size() const;

   Returns the number of elements in the local buffer.
