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:
  // construct/copy/destruct
  local_buffer(const size_t);
  local_buffer(const local_buffer &);
  local_buffer & operator=(const local_buffer &);
  ~local_buffer();

  // public member functions
  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));

  3. local_buffer & operator=(const local_buffer & other);
    Copies other to *this.
  4. ~local_buffer();
    Destroys the local memory object.
