如何使用Boost.Asio c？

文档可在此处找到：

http://www.boost.org/doc/libs/1_46_1/doc/html/boost_asio.html

您会发现许多应该满足您需求的示例.

对于构建,您应该注意,库依赖性取决于您是在Windows还是Linux上运行.看这里

http://www.boost.org/doc/libs/1_46_1/doc/html/boost_asio/using.html

特别是：

With MSVC or Borland C++ you may want
to add -DBOOST_DATE_TIME_NO_LIB and
-DBOOST_REGEX_NO_LIB to your project settings to disable autolinking of the
Boost.Date_Time and Boost.Regex
libraries respectively. Alternatively,
you may choose to build these
libraries and link to them

如果您不希望依赖于其他boost库,那么您可以从这里使用非boost(我认为是相同的asio)库：http://think-async.com/

对于其他文档的来源,请参阅SO：Best documentation for Boost:asio?上的这个问题

例如,要打开串口,您可能会编写如下内容：

/** Manage serial connections.*/
class serial_manager
{

  boost::asio::io_service m_io_service;
  std::string m_name;
  const unsigned int m_baud_rate;
  const enum flow_control::type m_flow_control;
  const enum parity::type m_parity;
  const enum stop_bits::type m_stop_bits;
  const unsigned int m_char_size;
  boost::asio::serial_port  m_SerialPort;
  boost::system::error_code m_error;
public:

  /** A constructor.
   *  @param name The dvice name,for example "COM1" (windows,or "/dev/ttyS0" (linux).
   *  @param baud_rate The baud rate. 
   *  @param flow_control The flow control. Acceptable values are flow_control::none,flow_control::software,flow_control::hardware.
   *  @param parity The parity of the connection. Acceptable values are parity::none,parity::even,parity::odd.
   *  @param stop_bits The number of stop bits. Acceptable values are stop_bits::one,stop_bits::one_point_five,stop::bits::two
   *  @param char_size The number of characters in connection.
   */
  serial_manager(const std::string& name,const unsigned int& baud_rate  = 19200,const enum flow_control::type&   flow_control  = flow_control::none,const enum parity::type&         parity        = parity::none,const enum stop_bits::type&      stop_bits     = stop_bits::one,const unsigned int& char_size  = 8
         ) 
;
  void open();
};

void
serial_manager::open() {
  if (!m_SerialPort.is_open()) 
    {
      m_SerialPort.open(m_name,m_error);

     if (m_error == boost::system::errc::no_such_file_or_directory ) 
     {  //for example you tried to open "COM1" on a linux machine.
        //... handle the error somehow
     }

      m_SerialPort.set_option(boost::asio::serial_port::baud_rate(m_baud_rate));
      m_SerialPort.set_option(boost::asio::serial_port::flow_control(m_flow_control));
      m_SerialPort.set_option(boost::asio::serial_port::parity(m_parity));
      m_SerialPort.set_option(boost::asio::serial_port::stop_bits(m_stop_bits));
      m_SerialPort.set_option(boost::asio::serial_port::character_size(m_char_size));
