+/*! \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;

+
+/*! \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 cl2.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 cl2.hpp.
+ *
+ * The bindings themselves are lightweight and correspond closely to the
+ * underlying C API. Using the C++ bindings introduces no additional execution
+ * overhead.
+ *
+ * There are numerous compatibility, portability and memory management
+ * fixes in the new header as well as additional OpenCL 2.0 features.
+ * As a result the header is not directly backward compatible and for this
+ * reason we release it as cl2.hpp rather than a new version of cl.hpp.
+ *
+ *
+ * \section compatibility Compatibility
+ * Due to the evolution of the underlying OpenCL API the 2.0 C++ bindings
+ * include an updated approach to defining supported feature versions
+ * and the range of valid underlying OpenCL runtime versions supported.
+ *
+ * The combination of preprocessor macros CL_HPP_TARGET_OPENCL_VERSION and
+ * CL_HPP_MINIMUM_OPENCL_VERSION control this range. These are three digit
+ * decimal values representing OpenCL runime versions. The default for
+ * the target is 200, representing OpenCL 2.0 and the minimum is also
+ * defined as 200. These settings would use 2.0 API calls only.
+ * If backward compatibility with a 1.2 runtime is required, the minimum
+ * version may be set to 120.
+ *
+ * Note that this is a compile-time setting, and so affects linking against
+ * a particular SDK version rather than the versioning of the loaded runtime.
+ *
+ * The earlier versions of the header included basic vector and string
+ * classes based loosely on STL versions. These were difficult to
+ * maintain and very rarely used. For the 2.0 header we now assume
+ * the presence of the standard library unless requested otherwise.
+ * We use std::array, std::vector, std::shared_ptr and std::string
+ * throughout to safely manage memory and reduce the chance of a
+ * recurrance of earlier memory management bugs.
+ *
+ * These classes are used through typedefs in the cl namespace:
+ * cl::array, cl::vector, cl::pointer and cl::string.
+ * In addition cl::allocate_pointer forwards to std::allocate_shared
+ * by default.
+ * In all cases these standard library classes can be replaced with
+ * custom interface-compatible versions using the CL_HPP_NO_STD_ARRAY,
+ * CL_HPP_NO_STD_VECTOR, CL_HPP_NO_STD_UNIQUE_PTR and
+ * CL_HPP_NO_STD_STRING macros.
+ *
+ * The OpenCL 1.x versions of the C++ bindings included a size_t wrapper
+ * class to interface with kernel enqueue. This caused unpleasant interactions
+ * with the standard size_t declaration and led to namespacing bugs.
+ * In the 2.0 version we have replaced this with a std::array-based interface.
+ * However, the old behaviour can be regained for backward compatibility
+ * using the CL_HPP_ENABLE_SIZE_T_COMPATIBILITY macro.
+ *
+ * Finally, the program construction interface used a clumsy vector-of-pairs
+ * design in the earlier versions. We have replaced that with a cleaner
+ * vector-of-vectors and vector-of-strings design. However, for backward
+ * compatibility old behaviour can be regained with the
+ * CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY macro.
+ *
+ * In OpenCL 2.0 OpenCL C is not entirely backward compatibility with
+ * earlier versions. As a result a flag must be passed to the OpenCL C
+ * compiled to request OpenCL 2.0 compilation of kernels with 1.2 as
+ * the default in the absence of the flag.
+ * In some cases the C++ bindings automatically compile code for ease.
+ * For those cases the compilation defaults to OpenCL C 2.0.
+ * If this is not wanted, the CL_HPP_CL_1_2_DEFAULT_BUILD macro may
+ * be specified to assume 1.2 compilation.
+ * If more fine-grained decisions on a per-kernel bases are required
+ * then explicit build operations that take the flag should be used.
+ *
+ *
+ * \section parameterization Parameters
+ * This header may be parameterized by a set of preprocessor macros.
+ *
+ * - CL_HPP_TARGET_OPENCL_VERSION
+ *
+ * Defines the target OpenCL runtime version to build the header
+ * against. Defaults to 200, representing OpenCL 2.0.
+ *
+ * - CL_HPP_NO_STD_STRING
+ *
+ * Do not use the standard library string class. cl::string is not
+ * defined and may be defined by the user before cl2.hpp is
+ * included.
+ *
+ * - CL_HPP_NO_STD_VECTOR
+ *
+ * Do not use the standard library vector class. cl::vector is not
+ * defined and may be defined by the user before cl2.hpp is
+ * included.
+ *
+ * - CL_HPP_NO_STD_ARRAY
+ *
+ * Do not use the standard library array class. cl::array is not
+ * defined and may be defined by the user before cl2.hpp is
+ * included.
+ *
+ * - CL_HPP_NO_STD_UNIQUE_PTR
+ *
+ * Do not use the standard library unique_ptr class. cl::pointer and
+ * the cl::allocate_pointer functions are not defined and may be
+ * defined by the user before cl2.hpp is included.
+ *
+ * - CL_HPP_ENABLE_DEVICE_FISSION
+ *
+ * Enables device fission for OpenCL 1.2 platforms.
+ *
+ * - CL_HPP_ENABLE_EXCEPTIONS
+ *
+ * Enable exceptions for use in the C++ bindings header. This is the
+ * preferred error handling mechanism but is not required.
+ *
+ * - CL_HPP_ENABLE_SIZE_T_COMPATIBILITY
+ *
+ * Backward compatibility option to support cl.hpp-style size_t
+ * class. Replaces the updated std::array derived version and
+ * removal of size_t from the namespace. Note that in this case the
+ * new size_t class is placed in the cl::compatibility namespace and
+ * thus requires an additional using declaration for direct backward
+ * compatibility.
+ *
+ * - CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY
+ *
+ * Enable older vector of pairs interface for construction of
+ * programs.
+ *
+ * - CL_HPP_CL_1_2_DEFAULT_BUILD
+ *
+ * Default to OpenCL C 1.2 compilation rather than OpenCL C 2.0
+ * applies to use of cl::Program construction and other program
+ * build variants.
+ *
+ *
+ * \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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
