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 - * #else - * #include - * #endif - * #include - * #include - * #include - * - * const char * helloStr = "__kernel void " - * "hello(void) " - * "{ " - * " " - * "} "; - * - * int - * main(void) - * { - * cl_int err = CL_SUCCESS; - * try { - * - * std::vector 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 devices = context.getInfo(); - * - * 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; - * } - * - * \endcode - * - */ -#ifndef CL_HPP_ -#define CL_HPP_ - -#ifdef _WIN32 - -#include -#include -#include -#include - -#if defined(__CL_ENABLE_EXCEPTIONS) -#include -#endif // #if defined(__CL_ENABLE_EXCEPTIONS) - -#pragma push_macro("max") -#undef max -#if defined(USE_DX_INTEROP) -#include -#include -#endif -#endif // _WIN32 - -// -#if defined(USE_CL_DEVICE_FISSION) -#include -#endif - -#if defined(__APPLE__) || defined(__MACOSX) -#include -#include -#include -#else -#include -#include -#endif // !__APPLE__ - -// To avoid accidentally taking ownership of core OpenCL types -// such as cl_kernel constructors are made explicit -// under OpenCL 1.2 -#if defined(CL_VERSION_1_2) && !defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) -#define __CL_EXPLICIT_CONSTRUCTORS explicit -#else // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) -#define __CL_EXPLICIT_CONSTRUCTORS -#endif // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) - -// Define deprecated prefixes and suffixes to ensure compilation -// in case they are not pre-defined -#if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) -#define CL_EXT_PREFIX__VERSION_1_1_DEPRECATED -#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) -#if !defined(CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED) -#define CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED -#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) - -#if !defined(CL_CALLBACK) -#define CL_CALLBACK -#endif //CL_CALLBACK - -#include -#include - -#if !defined(__NO_STD_VECTOR) -#include -#endif - -#if !defined(__NO_STD_STRING) -#include -#endif - -#if defined(linux) || defined(__APPLE__) || defined(__MACOSX) -#include - -#include -#include -#endif // linux - -#include - - -/*! \namespace cl - * - * \brief The OpenCL C++ bindings are defined within this namespace. - * - */ -namespace cl { - -class Memory; - -/** - * Deprecated APIs for 1.2 - */ -#if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) || (defined(CL_VERSION_1_1) && !defined(CL_VERSION_1_2)) -#define __INIT_CL_EXT_FCN_PTR(name) \ - if(!pfn_##name) { \ - pfn_##name = (PFN_##name) \ - clGetExtensionFunctionAddress(#name); \ - if(!pfn_##name) { \ - } \ - } -#endif // #if defined(CL_VERSION_1_1) - -#if defined(CL_VERSION_1_2) -#define __INIT_CL_EXT_FCN_PTR_PLATFORM(platform, name) \ - if(!pfn_##name) { \ - pfn_##name = (PFN_##name) \ - clGetExtensionFunctionAddressForPlatform(platform, #name); \ - if(!pfn_##name) { \ - } \ - } -#endif // #if defined(CL_VERSION_1_1) - -class Program; -class Device; -class Context; -class CommandQueue; -class Memory; -class Buffer; - -#if defined(__CL_ENABLE_EXCEPTIONS) -/*! \brief Exception class - * - * This may be thrown by API functions when __CL_ENABLE_EXCEPTIONS is defined. - */ -class Error : public std::exception -{ -private: - cl_int err_; - const char * errStr_; -public: - /*! \brief Create a new CL error exception for a given error code - * and corresponding message. - * - * \param err error code value. - * - * \param errStr a descriptive string that must remain in scope until - * handling of the exception has concluded.

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 + * #else + * #include + * #endif + * #include + * #include + * #include + * + * const char * helloStr = "__kernel void " + * "hello(void) " + * "{ " + * " " + * "} "; + * + * int + * main(void) + * { + * cl_int err = CL_SUCCESS; + * try { + * + * std::vector 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 devices = context.getInfo(); + * + * 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; + * } + * + * \endcode + * + */ +#ifndef CL_HPP_ +#define CL_HPP_ + +#ifdef _WIN32 + +#include +#include +#include +#include + +#if defined(__CL_ENABLE_EXCEPTIONS) +#include +#endif // #if defined(__CL_ENABLE_EXCEPTIONS) + +#pragma push_macro("max") +#undef max +#if defined(USE_DX_INTEROP) +#include +#include +#endif +#endif // _WIN32 + +// +#if defined(USE_CL_DEVICE_FISSION) +#include +#endif + +#if defined(__APPLE__) || defined(__MACOSX) +#include +#include +#include +#else +#include +#include +#endif // !__APPLE__ + +// To avoid accidentally taking ownership of core OpenCL types +// such as cl_kernel constructors are made explicit +// under OpenCL 1.2 +#if defined(CL_VERSION_1_2) && !defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) +#define __CL_EXPLICIT_CONSTRUCTORS explicit +#else // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) +#define __CL_EXPLICIT_CONSTRUCTORS +#endif // #if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) + +// Define deprecated prefixes and suffixes to ensure compilation +// in case they are not pre-defined +#if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) +#define CL_EXT_PREFIX__VERSION_1_1_DEPRECATED +#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) +#if !defined(CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED) +#define CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED +#endif // #if !defined(CL_EXT_PREFIX__VERSION_1_1_DEPRECATED) + +#if !defined(CL_CALLBACK) +#define CL_CALLBACK +#endif //CL_CALLBACK + +#include +#include + +#if !defined(__NO_STD_VECTOR) +#include +#endif + +#if !defined(__NO_STD_STRING) +#include +#endif + +#if defined(linux) || defined(__APPLE__) || defined(__MACOSX) +#include + +#include +#include +#endif // linux + +#include + + +/*! \namespace cl + * + * \brief The OpenCL C++ bindings are defined within this namespace. + * + */ +namespace cl { + +class Memory; + +/** + * Deprecated APIs for 1.2 + */ +#if defined(CL_USE_DEPRECATED_OPENCL_1_1_APIS) || (defined(CL_VERSION_1_1) && !defined(CL_VERSION_1_2)) +#define __INIT_CL_EXT_FCN_PTR(name) \ + if(!pfn_##name) { \ + pfn_##name = (PFN_##name) \ + clGetExtensionFunctionAddress(#name); \ + if(!pfn_##name) { \ + } \ + } +#endif // #if defined(CL_VERSION_1_1) + +#if defined(CL_VERSION_1_2) +#define __INIT_CL_EXT_FCN_PTR_PLATFORM(platform, name) \ + if(!pfn_##name) { \ + pfn_##name = (PFN_##name) \ + clGetExtensionFunctionAddressForPlatform(platform, #name); \ + if(!pfn_##name) { \ + } \ + } +#endif // #if defined(CL_VERSION_1_1) + +class Program; +class Device; +class Context; +class CommandQueue; +class Memory; +class Buffer; + +#if defined(__CL_ENABLE_EXCEPTIONS) +/*! \brief Exception class + * + * This may be thrown by API functions when __CL_ENABLE_EXCEPTIONS is defined. + */ +class Error : public std::exception +{ +private: + cl_int err_; + const char * errStr_; +public: + /*! \brief Create a new CL error exception for a given error code + * and corresponding message. + * + * \param err error code value. + * + * \param errStr a descriptive string that must remain in scope until + * handling of the exception has concluded.
