#includeIn this example, we create a buffer with a size of 256 bytes and then use it to store the string "Hello world!". We then print out the contents of the buffer and release the memory used by the buffer. Other package libraries that can be used for buffer data in C++ include the C++ Standard Library and the Poco C++ Libraries.int main() { //create a buffer with a size of 256 bytes boost::asio::mutable_buffer b = boost::asio::buffer(new char[256], 256); //use the buffer to store data char* buffer_data = boost::asio::buffer_cast (b); std::memcpy(buffer_data, "Hello world!", 12); //print out the data stored in the buffer std::cout << boost::asio::buffer_cast (b) << std::endl; //release the buffer memory delete[] boost::asio::buffer_cast (b); return 0; }
