    help with binary strings?

    Hey all, Sorry for the burden but you might as well welcome another C newb. Dah.

    Anyway, I'm extending the Ruby language and defining a new Ruby object(AMFSerializer). I'm going to be able to pass Ruby values to methods on that Ruby object.. that in the C code implement the functionality.

    What its doing is passing Ruby values and serializing those values into a binary AMF form. AMF is for the Flash player object format. I don't have a problem understanding the Ruby C API. More or less what I'm having troubles with is finding everything needed to do this with C.. I haven't written a lick of C so I need a little push in the right direction is all. With some more questions here and there..

    So I guess here is the first question::

    if I take a ruby value into a C function:

    Code:
    static VALUE write_amf3_string(VALUE self, VALUE str)
    {
      //where do I get an api for writing binary value to strings?
    }
    hmmmmm.
    Thanks

    You'll have to write the simple function yourself. Exactly what kind of value is self? How is VALUE defined?
    If you understand what you're doing, you're not learning anything.

    VALUE represents any ruby object. "VALUE str" would be a ruby string. I realize I have to write one myself. Is there C libraries or something I need to use? I guess i'm just lost not knowing any C. dah.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    So what you should be doing is approaching the problem from the other end.

    Start by going through some of the tutorials on this site, then asking questions about them when you get stuck.
