Key Constants & Config Struct

Key Constants

Defined in nsb.h:

#define SERVER_CONNECTION_TIMEOUT  10    // seconds — TCP connection timeout
#define DAEMON_RESPONSE_TIMEOUT    30    // seconds — default response timeout
#define RECEIVE_BUFFER_SIZE        4096  // bytes
#define SEND_BUFFER_SIZE           4096  // bytes

Constant	Value	Meaning
SERVER_CONNECTION_TIMEOUT	10 seconds	TCP connection timeout
DAEMON_RESPONSE_TIMEOUT	30 seconds	Default response timeout used by receive() and fetch()
RECEIVE_BUFFER_SIZE	4096 bytes	Size of the internal receive buffer
SEND_BUFFER_SIZE	4096 bytes	Size of the internal send buffer

Config Struct

Populated automatically during client initialization from the daemon's INIT response.

struct Config {
    enum class SystemMode { PULL = 0, PUSH = 1 };
    enum class SimulatorMode { SYSTEM_WIDE = 0, PER_NODE = 1 };

    SystemMode SYSTEM_MODE;
    SimulatorMode SIMULATOR_MODE;
    bool USE_DB;
    std::string DB_ADDRESS;
    int DB_PORT;
    int DB_NUM;
};

Accessible via client.cfg after initialization.
