Howto initialise char array style string in constructor

Question

I have a class which I'm serialising to send over a unix socket and it has to have a string which I've stored as a char array. Can I initialise it in the constructor differently to how I've done it here?

typedef struct SerialFunctionStatus_t {
    SerialFunctionStatus_t() 
        : serial_rx_count(0), serial_tx_count(0), socket_rx_count(0), socket_tx_count(0) 
        { port[0] = '\0'; }
    uint32_t serial_rx_count;
    uint32_t serial_tx_count;
    uint32_t socket_rx_count;
    uint32_t socket_tx_count;
    char port[20];
} SerialFunctionStatus_t;

Thanks for that BKB. Can you tell I'm really a C programmer? — Matthew Smith

Put port() in the initializer list. This causes port to be 'value initialized' (12.6.2), which for arrays of builtins means zero initialized (8.5).

What are you talking about? port() is not in the initializer list. Or did he edit his post?
