Hi boost users
I'm a newbie to boost trying to use a serial port as an iostream.
While searching the archives I found a post by Rob Desbois (2008-01-18
13:02) trying to achive the same. Unfortunately the solution wasn't
posted.
This is what I got so far:
#include
#include
class serial_device
{
public:
typedef char char_type;
typedef boost::iostreams::bidirectional_device_tag category;
serial_device(boost::asio::io_service& io_service, const std::string&
port, int baudrate = 9600) :
serial_port(io_service, port)
{
typedef boost::asio::serial_port_base spb;
serial_port.set_option(spb::baud_rate(baudrate));
};
std::streamsize read(char* buf, std::streamsize n)
{
boost::asio::read(serial_port, boost::asio::buffer(buf, n));
}
std::streamsize write(const char* buf, std::streamsize n)
{
boost::asio::write(serial_port, boost::asio::buffer(buf, n));
}
private:
boost::asio::serial_port serial_port;
};
int main(void)
{
boost::asio::io_service io_service;
serial_device serial(io_service, "/dev/ttyS0", 115200);
//boost::iostreams::stream s(serial);
}
If I uncomment the last line it fails to compile:

Could anyone please explain what I'm doing wrong?
Thanks,
