Features ^

• Implemented as a C++ class
• Exposes a very simple interface
• Supports multi-packet responses
• Non-threaded, delays for larger reponses
• Connection timeout (default 4 seconds)

Notes about this implementation:

• This is not a standalone application.
• It works on UNIX systems only as of now.

Example Usage ^

Prints test.

srcon client = srcon("127.0.0.1", 27015, "password");
std::string response = client.send("echo test");
std::cout << response << std::endl;

Constructors ^

1. srcon(srcon_addr addr, int timeout=SRCON_DEFAULT_TIMEOUT)
   • addr — srcon_addr struct
   • timeout — connection timeout in seconds (defaults to 4)
2. srcon(std::string address, int port, std::string pass, int timeout=SRCON_DEFAULT_TIMEOUT)
   • address — address of the server
   • port — port of the server
   • pass — rcon password of the server
   • timeout — connection timeout in seconds (defaults to 4)

Address Structure ^

srcon_addr struct consists of:

1. std::string addr — address of the server
2. int port — port of the server
3. std::string pass — rcon password of the server

Multi-packet Response ^

Using a method by Koraktor as explained here.

After each SERVERDATA_EXECCOMMAND request, a SERVERDATA_RESPONSE_VALUE packet is sent, which is used as a terminator package. This adds overhead to communication, but assures a reliable reception of all responses. For lengths of over 1024 bytes, the thread halts to let the buffer get filled (0.5 seconds).
