A tuple of the form <tt>{void*, + * size_t}</tt> specifies a mutable (modifiable) region of memory. Similarly, a + * tuple of the form <tt>{const void*, size_t}</tt> specifies a const + * (non-modifiable) region of memory. These two forms correspond to the classes + * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion + * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the + * opposite conversion is not permitted. + * + * The simplest use case involves reading or writing a single buffer of a + * specified size: + * + * @code sock.send(boost::asio::buffer(data, size)); @endcode + * + * In the above example, the return value of boost::asio::buffer meets the + * requirements of the ConstBufferSequence concept so that it may be directly + * passed to the socket's write function. A buffer created for modifiable + * memory also meets the requirements of the MutableBufferSequence concept. + * + * An individual buffer may be created from a builtin array, std::vector or + * boost::array of POD elements. This helps prevent buffer overruns by + * automatically determining the size of the buffer: + * + * @code char d1[128]; + * size_t bytes_transferred = sock.receive(boost::asio::buffer(d1)); + * + * std::vector<char> d2(128); + * bytes_transferred = sock.receive(boost::asio::buffer(d2)); + * + * boost::array<char, 128> d3; + * bytes_transferred = sock.receive(boost::asio::buffer(d3)); @endcode + * + * In all three cases above, the buffers created are exactly 128 bytes long. + * Note that a vector is @e never automatically resized when creating or using + * a buffer. The buffer size is determined using the vector's <tt>size()</tt> + * member function, and not its capacity. + * + * @par Accessing Buffer Contents + * + * The contents of a buffer may be accessed using the boost::asio::buffer_size + * and boost::asio::buffer_cast functions: + * + * @code boost::asio::mutable_buffer b1 = ...; + * std::size_t s1 = boost::asio::buffer_size(b1); + * unsigned char* p1 = boost::asio::buffer_cast<unsigned char*>(b1); + * + * boost::asio::const_buffer b2 = ...; + * std::size_t s2 = boost::asio::buffer_size(b2); + * const void* p2 = boost::asio::buffer_cast<const void*>(b2); @endcode + * + * The boost::asio::buffer_cast function permits violations of type safety, so + * uses of it in application code should be carefully considered. + * + * @par Buffer Invalidation + * + * A buffer object does not have any ownership of the memory it refers to. It + * is the responsibility of the application to ensure the memory region remains + * valid until it is no longer required for an I/O operation. When the memory + * is no longer available, the buffer is said to have been invalidated. + * + * For the boost::asio::buffer overloads that accept an argument of type + * std::vector, the buffer objects returned are invalidated by any vector + * operation that also invalidates all references, pointers and iterators + * referring to the elements in the sequence (C++ Std, 23.2.4) + * + * For the boost::asio::buffer overloads that accept an argument of type + * std::string, the buffer objects returned are invalidated according to the + * rules defined for invalidation of references, pointers and iterators + * referring to elements of the sequence (C++ Std, 21.3). + * + * @par Buffer Arithmetic + * + * Buffer objects may be manipulated using simple arithmetic in a safe way + * which helps prevent buffer overruns. Consider an array initialised as + * follows: + * + * @code boost::array<char, 6> a = { 'a', 'b', 'c', 'd', 'e' }; @endcode + * + * A buffer object @c b1 created using: + * + * @code b1 = boost::asio::buffer(a); @endcode + * + * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An + * optional second argument to the boost::asio::buffer function may be used to + * limit the size, in bytes, of the buffer: + * + * @code b2 = boost::asio::buffer(a, 3); @endcode + * + * such that @c b2 represents the data <tt>{ 'a', 'b', 'c' }</tt>. Even if the + * size argument exceeds the actual size of the array, the size of the buffer + * object created will be limited to the array size. + * + * An offset may be applied to an existing buffer to create a new one: + * + * @code b3 = b1 + 2; @endcode + * + * where @c b3 will set to represent <tt>{ 'c', 'd', 'e' }</tt>. If the offset + * exceeds the size of the existing buffer, the newly created buffer will be + * empty. + * + * Both an offset and size may be specified to create a buffer that corresponds + * to a specific range of bytes within an existing buffer: + * + * @code b4 = boost::asio::buffer(b1 + 1, 3); @endcode + * + * so that @c b4 will refer to the bytes <tt>{ 'b', 'c', 'd' }</tt>. + * + * @par Buffers and Scatter-Gather I/O + * + * To read or write using multiple buffers (i.e. scatter-gather I/O), multiple + * buffer objects may be assigned into a container that supports the + * MutableBufferSequence (for read) or ConstBufferSequence (for write) concepts: + * + * @code + * char d1[128]; + * std::vector<char> d2(128); + * boost::array<char, 128> d3; + * + * boost::array<mutable_buffer, 3> bufs1 = { + * boost::asio::buffer(d1), + * boost::asio::buffer(d2), + * boost::asio::buffer(d3) }; + * bytes_transferred = sock.receive(bufs1); + * + * std::vector<const_buffer> bufs2; + * bufs2.push_back(boost::asio::buffer(d1)); + * bufs2.push_back(boost::asio::buffer(d2)); + * bufs2.push_back(boost::asio::buffer(d3)); + * bytes_transferred = sock.send(bufs2); @endcode + */ +/*@{*/ + +/// Create a new modifiable buffer from an existing buffer. +/** + * @returns <tt>mutable_buffers_1(b)</tt>. + */ +inline mutable_buffers_1 buffer(const mutable_buffer& b) +{ + return mutable_buffers_1(b); +} + +/// Create a new modifiable buffer from an existing buffer. +/** + * @returns A mutable_buffers_1 value equivalent to: + * @code mutable_buffers_1( + * buffer_cast<void*>(b), + * min(buffer_size(b), max_size_in_bytes)); @endcode + */ +inline mutable_buffers_1 buffer(const mutable_buffer& b, + std::size_t max_size_in_bytes) +{ + return mutable_buffers_1( + mutable_buffer(buffer_cast<void*>(b), + buffer_size(b) < max_size_in_bytes + ? buffer_size(b) : max_size_in_bytes +#if defined(BOOST_ASIO_ENABLE_BUFFER_DEBUGGING) + , b.get_debug_check() +#endif // BOOST_ASIO_ENABLE_BUFFER_DEBUGGING + )); +} + +/// Create a new non-modifiable buffer from an existing buffer. +/** + * @returns <tt>const_buffers_1(b)</tt>. + */ +inline const_buffers_1 buffer(const const_buffer& b) +{ + return const_buffers_1(b); +} + +/// Create a new non-modifiable buffer from an existing buffer. +/** + * @returns A const_buffers_1 value equivalent to: + * @code const_buffers_1( + * buffer_cast<const void*>(b), + * min(buffer_size(b), max_size_in_bytes)); @endcode + */ +inline const_buffers_1 buffer(const const_buffer& b, + std::size_t max_size_in_bytes) +{ + return const_buffers_1( + const_buffer(buffer_cast<const void*>(b), + buffer_size(b) < max_size_in_bytes + ? buffer_size(b) : max_size_in_bytes +#if defined(BOOST_ASIO_ENABLE_BUFFER_DEBUGGING) + , b.get_debug_check() +#endif // BOOST_ASIO_ENABLE_BUFFER_DEBUGGING + )); +} + +/// Create a new modifiable buffer that represents the given memory range. +/** + * @returns <tt>mutable_buffers_1(data, size_in_bytes)</tt>. + */ +inline mutable_buffers_1 buffer(void* data, std::size_t size_in_bytes) +{ + return mutable_buffers_1(mutable_buffer(data, size_in_bytes)); +} + +/// Create a new non-modifiable buffer that represents the given memory range. +/** + * @returns <tt>const_buffers_1(data, size_in_bytes)</tt>. + */ +inline const_buffers_1 buffer(const void* data, + std::size_t size_in_bytes) +{ + return const_buffers_1(const_buffer(data, size_in_bytes)); +} + +/// Create a new modifiable buffer that represents the given POD array. +/** + * @returns A mutable_buffers_1 value equivalent to: + * @code mutable_buffers_1( + * static_cast<void*>(data), + * N * sizeof(PodType)); @endcode + */ +template <typename PodType, std::size_t N> +inline mutable_buffers_1 buffer(PodType (&data)[N]) +{ + return mutable_buffers_1(mutable_buffer(data, N * sizeof(PodType))); +} + +/// Create a new modifiable buffer that represents the given POD array. +/** + * @returns A mutable_buffers_1 value equivalent to: + * @code mutable_buffers_1( + * static_cast<void*>(data), + * min(N * sizeof(PodType), max_size_in_bytes)); @endcode + */ +template <typename PodType, std::size_t N> +inline mutable_buffers_1 buffer(PodType (&data)[N], + std::size_t max_size_in_bytes) +{ + return mutable_buffers_1( + mutable_buffer(data, + N * sizeof(PodType) < max_size_in_bytes + ?
