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(asio::buffer(data, size)); @endcode - * - * In the above example, the return value of 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, - * std::array 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(asio::buffer(d1)); - * - * std::vector<char> d2(128); - * bytes_transferred = sock.receive(asio::buffer(d2)); - * - * std::array<char, 128> d3; - * bytes_transferred = sock.receive(asio::buffer(d3)); - * - * boost::array<char, 128> d4; - * bytes_transferred = sock.receive(asio::buffer(d4)); @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 @ref buffer_size and - * @ref buffer_cast functions: - * - * @code asio::mutable_buffer b1 = ...; - * std::size_t s1 = asio::buffer_size(b1); - * unsigned char* p1 = asio::buffer_cast<unsigned char*>(b1); - * - * asio::const_buffer b2 = ...; - * std::size_t s2 = asio::buffer_size(b2); - * const void* p2 = asio::buffer_cast<const void*>(b2); @endcode - * - * The asio::buffer_cast function permits violations of type safety, so - * uses of it in application code should be carefully considered. - * - * For convenience, the @ref buffer_size function also works on buffer - * sequences (that is, types meeting the ConstBufferSequence or - * MutableBufferSequence type requirements). In this case, the function returns - * the total size of all buffers in the sequence. - * - * @par Buffer Copying - * - * The @ref buffer_copy function may be used to copy raw bytes between - * individual buffers and buffer sequences. - * - * In particular, when used with the @ref buffer_size, the @ref buffer_copy - * function can be used to linearise a sequence of buffers. For example: - * - * @code vector<const_buffer> buffers = ...; - * - * vector<unsigned char> data(asio::buffer_size(buffers)); - * asio::buffer_copy(asio::buffer(data), buffers); @endcode - * - * Note that @ref buffer_copy is implemented in terms of @c memcpy, and - * consequently it cannot be used to copy between overlapping memory regions. - * - * @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 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 asio::buffer overloads that accept an argument of type - * std::basic_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 = asio::buffer(a); @endcode - * - * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An - * optional second argument to the asio::buffer function may be used to - * limit the size, in bytes, of the buffer: - * - * @code b2 = 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 = 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 = { - * asio::buffer(d1), - * asio::buffer(d2), - * asio::buffer(d3) }; - * bytes_transferred = sock.receive(bufs1); - * - * std::vector<const_buffer> bufs2; - * bufs2.push_back(asio::buffer(d1)); - * bufs2.push_back(asio::buffer(d2)); - * bufs2.push_back(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(ASIO_ENABLE_BUFFER_DEBUGGING) - , b.get_debug_check() -#endif // 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(ASIO_ENABLE_BUFFER_DEBUGGING) - , b.get_debug_check() -#endif // 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 - ?
