/*! \mainpage
* \section intro Introduction
* For many large applications C++ is the language of choice and so it seems
* reasonable to define C++ bindings for OpenCL.
*
*
* The interface is contained with a single C++ header file \em cl.hpp and all
* definitions are contained within the namespace \em cl. There is no additional
* requirement to include \em cl.h and to use either the C++ or original C
* bindings it is enough to simply include \em cl.hpp.
*
* The bindings themselves are lightweight and correspond closely to the
* underlying C API. Using the C++ bindings introduces no additional execution
* overhead.
*
* For detail documentation on the bindings see:
*
* The OpenCL C++ Wrapper API 1.2 (revision 09)
* http://www.khronos.org/registry/cl/specs/opencl-cplusplus-1.2.pdf
*
* \section example Example
*
* The following example shows a general use case for the C++
* bindings, including support for the optional exception feature and
* also the supplied vector and string classes, see following sections for
* decriptions of these features.
*
* \code
* #define __CL_ENABLE_EXCEPTIONS
*
* #if defined(__APPLE__) || defined(__MACOSX)
* #include <OpenCL/cl.hpp>
* #else
* #include <CL/cl.hpp>
* #endif
* #include <cstdio>
* #include <cstdlib>
* #include <iostream>
*
* const char * helloStr = "__kernel void "
* "hello(void) "
* "{ "
* " "
* "} ";
*
* int
* main(void)
* {
* cl_int err = CL_SUCCESS;
* try {
*
* std::vector<cl::Platform> platforms;
* cl::Platform::get(&platforms);
* if (platforms.size() == 0) {
* std::cout << "Platform size 0\n";
* return -1;
* }
*
* cl_context_properties properties[] =
* { CL_CONTEXT_PLATFORM, (cl_context_properties)(platforms[0])(), 0};
* cl::Context context(CL_DEVICE_TYPE_CPU, properties);
*
* std::vector<cl::Device> devices = context.getInfo<CL_CONTEXT_DEVICES>();
*
* cl::Program::Sources source(1,
* std::make_pair(helloStr,strlen(helloStr)));
* cl::Program program_ = cl::Program(context, source);
* program_.build(devices);
*
* cl::Kernel kernel(program_, "hello", &err);
*
* cl::Event event;
* cl::CommandQueue queue(context, devices[0], 0, &err);
* queue.enqueueNDRangeKernel(
* kernel,
* cl::NullRange,
* cl::NDRange(4,4),
* cl::NullRange,
* NULL,
* &event);
*
* event.wait();
* }
* catch (cl::Error err) {
* std::cerr
* << "ERROR: "
* << err.what()
* << "("
* << err.err()
* << ")"
* << std::endl;
* }
*
* return EXIT_SUCCESS;
* }
