Method platforms

compute/include/boost/compute/system.hpp:186–202

Returns a vector containing each of the OpenCL platforms on the system. For example, to print out the name of each OpenCL platform present on the system: \code for(const auto &platform : boost::compute::system::platforms()){ std::cout << platform.name() << std::endl; } \endcode

    /// }
    /// \endcode
    static std::vector<platform> platforms()
    {
        cl_uint count = 0;
        clGetPlatformIDs(0, 0, &count);

        std::vector<platform> platforms;
        if(count > 0)
        {
            std::vector<cl_platform_id> platform_ids(count);
            clGetPlatformIDs(count, &platform_ids[0], 0);

            for(size_t i = 0; i < platform_ids.size(); i++){
                platforms.push_back(platform(platform_ids[i]));
            }
        }
        return platforms;
    }

    /// Returns the number of compute platforms on the system.
