to create a buffer object to- * represent raw memory, an array of POD elements, a vector of POD elements,- * or a std::string.- *- * A buffer object represents a contiguous region of memory as a 2-tuple- * consisting of a pointer and size in bytes. 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 @c data() and @c size()- * member functions:- *- * @code asio::mutable_buffer b1 = ...;- * std::size_t s1 = b1.size();- * unsigned char* p1 = static_cast<unsigned char*>(b1.data());- *- * asio::const_buffer b2 = ...;- * std::size_t s2 = b2.size();- * const void* p2 = b2.data(); @endcode- *- * The @c data() member function permits violations of type safety, so- * uses of it in application code should be carefully considered.- *- * For convenience, a @ref buffer_size function is provided that works with- * both buffers and 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 function, 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- *- * @par Buffer Literals- *- * The `_buf` literal suffix, defined in namespace- * <tt>asio::buffer_literals</tt>, may be used to create @c const_buffer- * objects from string, binary integer, and hexadecimal integer literals.- * For example:- *- * @code- * using namespace asio::buffer_literals;- *- * asio::const_buffer b1 = "hello"_buf;- * asio::const_buffer b2 = 0xdeadbeef_buf;- * asio::const_buffer b3 = 0x0123456789abcdef0123456789abcdef_buf;- * asio::const_buffer b4 = 0b1010101011001100_buf; @endcode- *- * Note that the memory associated with a buffer literal is valid for the- * lifetime of the program. This means that the buffer can be safely used with- * asynchronous operations.- */-/*@{*/--/// Create a new modifiable buffer from an existing buffer.-/**- * @returns <tt>mutable_buffer(b)</tt>.- */-ASIO_NODISCARD inline mutable_buffer buffer(-    const mutable_buffer& b) noexcept-{-  return mutable_buffer(b);-}--/// Create a new modifiable buffer from an existing buffer.-/**- * @returns A mutable_buffer value equivalent to:- * @code mutable_buffer(- *     b.data(),- *     min(b.size(), max_size_in_bytes)); @endcode- */-ASIO_NODISCARD inline mutable_buffer buffer(-    const mutable_buffer& b,-    std::size_t max_size_in_bytes) noexcept-{-  return mutable_buffer(-      mutable_buffer(b.data(),-        b.size() < max_size_in_bytes-        ? b.size() : 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_buffer(b)</tt>.- */-ASIO_NODISCARD inline const_buffer buffer(-    const const_buffer& b) noexcept-{-  return const_buffer(b);-}--/// Create a new non-modifiable buffer from an existing buffer.-/**- * @returns A const_buffer value equivalent to:- * @code const_buffer(- *     b.data(),- *     min(b.size(), max_size_in_bytes)); @endcode- */-ASIO_NODISCARD inline const_buffer buffer(-    const const_buffer& b,-    std::size_t max_size_in_bytes) noexcept-{-  return const_buffer(b.data(),-      b.size() < max_size_in_bytes-      ? b.size() : 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_buffer(data, size_in_bytes)</tt>.- */-ASIO_NODISCARD inline mutable_buffer buffer(-    void* data, std::size_t size_in_bytes) noexcept-{-  return mutable_buffer(data, size_in_bytes);-}--/// Create a new non-modifiable buffer that represents the given memory range.-/**- * @returns <tt>const_buffer(data, size_in_bytes)</tt>.- */-ASIO_NODISCARD inline const_buffer buffer(-    const void* data, std::size_t size_in_bytes) noexcept-{-  return const_buffer(data, size_in_bytes);-}--/// Create a new modifiable buffer that represents the given POD array.-/**- * @returns A mutable_buffer value equivalent to:- * @code mutable_buffer(- *     static_cast<void*>(data),- *     N * sizeof(PodType)); @endcode- */-template <typename PodType, std::size_t N>-ASIO_NODISCARD inline mutable_buffer buffer(-    PodType (&data)[N]) noexcept-{-  return mutable_buffer(data, N * sizeof(PodType));-}--/// Create a new modifiable buffer that represents the given POD array.-/**- * @returns A mutable_buffer value equivalent to:- * @code mutable_buffer(- *     static_cast<void*>(data),- *     min(N * sizeof(PodType), max_size_in_bytes)); @endcode- */-template <typename PodType, std::size_t N>-ASIO_NODISCARD inline mutable_buffer buffer(-    PodType (&data)[N],-    std::size_t max_size_in_bytes) noexcept-{-  return mutable_buffer(data,-      N * sizeof(PodType) < max_size_in_bytes-      ?

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 @c data() and @c size()+ * member functions:+ *+ * @code asio::mutable_buffer b1 = ...;+ * std::size_t s1 = b1.size();+ * unsigned char* p1 = static_cast<unsigned char*>(b1.data());+ *+ * asio::const_buffer b2 = ...;+ * std::size_t s2 = b2.size();+ * const void* p2 = b2.data(); @endcode+ *+ * The @c data() member function permits violations of type safety, so+ * uses of it in application code should be carefully considered.+ *+ * For convenience, a @ref buffer_size function is provided that works with+ * both buffers and 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 function, 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+ *+ * @par Buffer Literals+ *+ * The `_buf` literal suffix, defined in namespace+ * <tt>asio::buffer_literals</tt>, may be used to create @c const_buffer+ * objects from string, binary integer, and hexadecimal integer literals.+ * For example:+ *+ * @code+ * using namespace asio::buffer_literals;+ *+ * asio::const_buffer b1 = "hello"_buf;+ * asio::const_buffer b2 = 0xdeadbeef_buf;+ * asio::const_buffer b3 = 0x0123456789abcdef0123456789abcdef_buf;+ * asio::const_buffer b4 = 0b1010101011001100_buf; @endcode+ *+ * Note that the memory associated with a buffer literal is valid for the+ * lifetime of the program. This means that the buffer can be safely used with+ * asynchronous operations.+ */+/*@{*/++#if defined(ASIO_NO_DEPRECATED) || defined(GENERATING_DOCUMENTATION)+# define ASIO_MUTABLE_BUFFER mutable_buffer+# define ASIO_CONST_BUFFER const_buffer+#else // defined(ASIO_NO_DEPRECATED) || defined(GENERATING_DOCUMENTATION)+# define ASIO_MUTABLE_BUFFER mutable_buffers_1+# define ASIO_CONST_BUFFER const_buffers_1+#endif // defined(ASIO_NO_DEPRECATED) || defined(GENERATING_DOCUMENTATION)++/// Create a new modifiable buffer from an existing buffer.+/**+ * @returns <tt>mutable_buffer(b)</tt>.+ */+ASIO_NODISCARD inline ASIO_MUTABLE_BUFFER buffer(+    const mutable_buffer& b) ASIO_NOEXCEPT+{+  return ASIO_MUTABLE_BUFFER(b);+}++/// Create a new modifiable buffer from an existing buffer.+/**+ * @returns A mutable_buffer value equivalent to:+ * @code mutable_buffer(+ *     b.data(),+ *     min(b.size(), max_size_in_bytes)); @endcode+ */+ASIO_NODISCARD inline ASIO_MUTABLE_BUFFER buffer(+    const mutable_buffer& b,+    std::size_t max_size_in_bytes) ASIO_NOEXCEPT+{+  return ASIO_MUTABLE_BUFFER(+      mutable_buffer(b.data(),+        b.size() < max_size_in_bytes+        ? b.size() : 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_buffer(b)</tt>.+ */+ASIO_NODISCARD inline ASIO_CONST_BUFFER buffer(+    const const_buffer& b) ASIO_NOEXCEPT+{+  return ASIO_CONST_BUFFER(b);+}++/// Create a new non-modifiable buffer from an existing buffer.+/**+ * @returns A const_buffer value equivalent to:+ * @code const_buffer(+ *     b.data(),+ *     min(b.size(), max_size_in_bytes)); @endcode+ */+ASIO_NODISCARD inline ASIO_CONST_BUFFER buffer(+    const const_buffer& b,+    std::size_t max_size_in_bytes) ASIO_NOEXCEPT+{+  return ASIO_CONST_BUFFER(b.data(),+      b.size() < max_size_in_bytes+      ? b.size() : 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_buffer(data, size_in_bytes)</tt>.+ */+ASIO_NODISCARD inline ASIO_MUTABLE_BUFFER buffer(+    void* data, std::size_t size_in_bytes) ASIO_NOEXCEPT+{+  return ASIO_MUTABLE_BUFFER(data, size_in_bytes);+}++/// Create a new non-modifiable buffer that represents the given memory range.+/**+ * @returns <tt>const_buffer(data, size_in_bytes)</tt>.+ */+ASIO_NODISCARD inline ASIO_CONST_BUFFER buffer(+    const void* data, std::size_t size_in_bytes) ASIO_NOEXCEPT+{+  return ASIO_CONST_BUFFER(data, size_in_bytes);+}++/// Create a new modifiable buffer that represents the given POD array.+/**+ * @returns A mutable_buffer value equivalent to:+ * @code mutable_buffer(+ *     static_cast<void*>(data),+ *     N * sizeof(PodType)); @endcode+ */+template <typename PodType, std::size_t N>+ASIO_NODISCARD inline ASIO_MUTABLE_BUFFER buffer(+    PodType (&data)[N]) ASIO_NOEXCEPT+{+  return ASIO_MUTABLE_BUFFER(data, N * sizeof(PodType));+}+ +/// Create a new modifiable buffer that represents the given POD array.+/**+ * @returns A mutable_buffer value equivalent to:+ * @code mutable_buffer(+ *     static_cast<void*>(data),+ *     min(N * sizeof(PodType), max_size_in_bytes)); @endcode+ */+template <typename PodType, std::size_t N>+ASIO_NODISCARD inline ASIO_MUTABLE_BUFFER buffer(+    PodType (&data)[N],+    std::size_t max_size_in_bytes) ASIO_NOEXCEPT+{+  return ASIO_MUTABLE_BUFFER(data,+      N * sizeof(PodType) < max_size_in_bytes+      ?

Default invoke+ * function for handlers.+ *+ * Completion handlers for asynchronous operations are invoked by the+ * io_context associated with the corresponding object (e.g. a socket or+ * deadline_timer). Certain guarantees are made on when the handler may be+ * invoked, in particular that a handler can only be invoked from a thread that+ * is currently calling @c run() on the corresponding io_context object.+ * Handlers may subsequently be invoked through other objects (such as+ * io_context::strand objects) that provide additional guarantees.+ *+ * When asynchronous operations are composed from other asynchronous+ * operations, all intermediate handlers should be invoked using the same+ * method as the final handler. This is required to ensure that user-defined+ * objects are not accessed in a way that may violate the guarantees. This+ * hooking function ensures that the invoked method used for the final handler+ * is accessible at each intermediate step.+ *+ * Implement asio_handler_invoke for your own handlers to specify a custom+ * invocation strategy.+ *+ * This default implementation invokes the function object like so:+ * @code function(); @endcode+ * If necessary, the default implementation makes a copy of the function object+ * so that the non-const operator() can be used.+ *+ * @par Example+ * @code+ * class my_handler;+ *+ * template <typename Function>+ * void asio_handler_invoke(Function function, my_handler* context)+ * {+ *   context->strand_.dispatch(function);+ * }+ * @endcode+ */+/*@{*/++#if defined(ASIO_NO_DEPRECATED)++// Places in asio that would have previously called the invocation hook to+// execute a handler, now call it only to check whether the result type is this+// type.
