[ENet-discuss] ENetPacket to std::string

[Nuno Silva]

First of all, be sure that the content you're getting is indeed a string.
Binary data does not go well with strings, because e.g., std::string may
find a '\0' before it reaches the end of the packet data which signifies an
end of string in C-Style strings, and thus not have all the data.

You could typecast that packet->data as (const char *)packet->data, however
it probably does not have an ending '\0', so you should first copy it to a
buffer and append a '\0' to that buffer. Something like this:

std::vector<char> myString(packet->dataLength + 1);
myString[packet->dataLength] = '\0';
memcpy(&myString[0], packet->data, packet->dataLength);

std::string my_string(&myString[0]);

Hope that helps.
