# checkport

a tiny tool lib written in c++ based on asio for iterating and checking tcp port.

## Usage

```

// define this to enable checkport header only mode

#define CHECK_PORT_HEADER_ONLY

#include "checkport.h"

#include 

int main(int argc, char** argv)

{

    // Constructor requires ip and port range.

    checkport::CheckPort cp("127.0.0.1", 1, 4000);

    // Set connect timeout.Consider fail if connecting port timeout.

    cp.SetConnectTimeout(1);

    // Set max concurrency.Increase this will improve check speed.

    cp.SetConcurrency(100);

    // Return 0 if no port is accessable in the port range

    // Or any number larger than 0 indicates the first accessable port in the range.

    auto port = cp.GetOne();

    if (port == 0)

        std::cout << "no port is accessable" << std::endl;

    else

        std::cout << port << " is accessable" << std::endl;

    // Return vector holds every accessable port in the range.

    auto port_list = cp.GetAll();

    for (const auto& v : port_list)

        std::cout << v << " ";

    return 0;

}
