    char v[2];
    scanf("%[^' '] %c", &v[0], &v[1]);

    Equivalent of sscanf

    I'm transitioning from C to C++ and am apparently having issues with certain things. In my C code, I have something that looks like this:

    Simple Color Picker with glReadPixel

    I'm trying to read the pixel at the user's cursor when they right click on a triangular gradient, but glReadPixel is only returning black. If I make it a flat color instead of a gradient, it works,...

    Ah! That makes sense, thank you very much.

    As a kind of follow up - if I was going to try to send the same data over a network, how would the server/client know that it's receiving a cMap...
  7. Error-checking a class read from a binary file

    I'm writing a certain class (the specifics don't really pertain to my question) to a file like so



    fwrite((void*)&Map[MapID], sizeof(cMap), 1, fp);


    And I read it later like so
  8. Does __attribute__ ((destructor)) run on crash?

    Will gcc's deconstructor still run if the program crashes (due to a segfault or whatever else), or only on a successful exit or end of main?

    std::string.assign segfault

    I use a std::string inside of a class I allocate dynamically, and I crash or get segfaults whenever I try to use the string. I assume I'm not initializing it right somehow, but I don't know what to...
  12. TTF_Font to GL Display List Kerning issue

    Forgot to mention that although the font looks like it has an outline, that's just part of the font. The actual true-type font looks like that, haha. Also, I can end up with it looking like this...
