How to io_control of boost library socket with customized command - boost-asio

Question

I' trying to make an identical function to "ioctl" in c++ style using boost library.
Here is my "c" style code:
int sockfd;
char * id;
struct iwreq wreq;
memset(&wreq, 0, sizeof(struct iwreq));
sprintf(wreq.ifr_name, IW_INTERFACE);
if((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) == -1) {
fprintf(stderr, "Cannot open socket \n");
fprintf(stderr, "errno = %d \n", errno);
fprintf(stderr, "Error description is : %s\n",strerror(errno));
exit(1);
}
printf("Socket opened successfully \n");
id = malloc(IW_ESSID_MAX_SIZE+1);
wreq.u.essid.pointer = id;
if (ioctl(sockfd, SIOCGIWESSID, &wreq)) {
fprintf(stderr, "Get ESSID ioctl failed \n");
fprintf(stderr, "errno = %d \n", errno);
fprintf(stderr, "Error description : %s\n",strerror(errno));
exit(2);
}
printf("IOCTL Successfull\n");
printf("ESSID is %s\n", wreq.u.essid.pointer);
I found some relevant example, but I'm not clear how to use it correctly. example
Main function:
boost::asio::ip::udp::socket socket(io_service);
struct iwreq wreq
memset(&wreq, 0, sizeof(struct iwreq));
sprintf(wreq.ifr_name, IW_INTERFACE);
id = malloc(IW_ESSID_MAX_SIZE+1);
wreq.u.essid.pointer = id;
boost::asio::detail::io_control::myCommand command;
command.set(&wreq);
boost::system::error_code ec;
socket.io_control(command, ec);
if (ec)
{
// An error occurred.
}
Custom command:
#include <boost/asio/detail/config.hpp>
#include <cstddef>
#include <boost/config.hpp>
#include <boost/asio/detail/socket_types.hpp>
#include <boost/asio/detail/push_options.hpp>
namespace boost {
namespace asio {
namespace detail {
namespace io_control {
// I/O control command for getting number of bytes available.
class myCommand
{
public:
// Default constructor.
myCommand()
: value_(0)
{
}
// Get the name of the IO control command.
int name() const
{
return static_cast<int>(SIOCGIWESSID);
}
// Set the value of the I/O control command.
void set(struct iwreq* value)
{
value_ = static_cast<detail::ioctl_arg_type>(value);
}
// Get the current value of the I/O control command.
std::size_t get() const
{
return static_cast<struct iwreq*>(value_);
}
// Get the address of the command data.
detail::ioctl_arg_type* data()
{
return &value_;
}
// Get the address of the command data.
const detail::ioctl_arg_type* data() const
{
return &value_;
}
private:
detail::ioctl_arg_type value_;
};
} // namespace io_control
} // namespace detail
} // namespace asio
} // namespace boost
However, the code does not work.
If you have any example code or solution, please let me know.
Thank you.
