Posts I've Made

  1. In Topic: TCP server/multiple client with select process and forking

    Posted 15 Sep 2014

    forking seems like overkill, select can tell you when a user wants to send something as well as when the client has received something. Just add the stdin and the server file descriptor to the select file descriptor set.
  2. In Topic: How do you null terminate a short?

    Posted 24 Jul 2014

    Are you attempting a C string into a short? A short is typcially two bytes, which would only leave you one byte for the character, and one for the NULL terminator. Doesn't really make much sense.
  3. In Topic: array of char* as function argument

    Posted 30 Jun 2014

    You cannot determine the size of an array simply based on a pointer.

    You have a few options:

    1) Pass the size of the array as a parameter
    2) Pass a vector of char* (instead of an array)
    3) Create your own struct which encapsulates the array of strings with the size
  4. In Topic: The Best Data Structure for a Dispatcher?

    Posted 12 Jun 2014

    I would be easier to answer your question if you explained why you need three separate queues.
  5. In Topic: Getting the size of an array

    Posted 12 Jun 2014

    sizeof give the size in bytes, however your number's array is of type int.

    Therefore, to get the number of elements in your array you need.

    sizeof(numbers) / sizeof(int)

    It looks like your numbers array is decaying to a pointer, therefore sizeof(numbers) evaluates to 4 bytes (since a pointer is 4 bytes on a 32 bit system). Try explicitly allocating memory for numbers.

    int numbers[6] = {8, 2, 0, 4, 100, 5};
        for(int i = 0; i < sizeof(numbers) / sizeof(int); i++){
                cout << numbers[i] << endl;
