How read recive data? (const void*)
« on: March 26, 2014, 07:10:57 pm »
Hello! I need to read the incoming packets.

I can not make it through sf::Packet, since the structure of the package is not known.
I need to convert the received packet data(const void*) to "classical" set bits in hex ​​format. (example: 00:00:00:04:00:00:00:0c:68:65:6c:6c:6f:20:73:65:72:76:65:72)

ps: by TcpSocket
I do not know much English.

Do you need to display the data in hexadecimal representation? Or do you just need it in another type (in this case you just need a cast)?

void* just means that the function can accept anything, but you're supposed to pass a typed variable, for example:

uint8_t data[10];
socket.receive(data, ...);
