Question

I am trying to write a socket system that is to handle extremely long messages (it handles a chat system). I am trying to use a const int to initialize an array, which DOES compile, but I am warned about ISO C++ forbidding it. Can someone shed some light on the situation?

Here is an example of how it would be used (this is to avoid writing a byte-remaining multi-recieve system (which I already have, but I feel this would be more efficient)).

    const int BUFFERLEN = atoi(api_GETVALUE(1,inbuffer).c_str()); //that is my API call
       if(BUFFERLEN != -1) { //it returns "-1" on error
          char INBUFFER[BUFFERLEN];
          recv(SOCK,INBUFFER,sizeof(INBUFFER),0);
       }

Is this acceptable to do at all, or should I stick with the multi-recieve-until-done method?

Thanks,
Collin

 const int BUFFERLEN = atoi(api_GETVALUE(1,inbuffer).c_str()); //that is my API call
       if(BUFFERLEN != -1) { //it returns "-1" on error
          std::vector<char> INBUFFER(BUFFERLEN);
          recv(SOCK,INBUFFER.data(),INBUFFER.size(),0);
       }
