title: (Dependency Walker) missing explicit type on function
body: <p>Apologies in advance for noob mistakes. This is my first question here. First, some background:</p>
  
  <p>I am trying to create a module for a program using dependency walker to find C++ functions in a .dll that I don't have the lib or any source code for. You can also assume that I can't get support from the original developer. Basically, I checked another file that accesses it to see what the minimum functions were to get it working. Here is an example of the undecorated names that are output:</p>
  
  <pre><code>void foo::bar::baz(float)
  float foo::bar::qux(void)
  foo::bar::bar(void)
  class foo::bar &amp; foo::bar::operator=(class foo::bar const &amp;)
  </code></pre>
  
  <p>The top two functions obviously take float or void and return float or void. I got a similar function working using something like:</p>
  
  <pre><code>HINSTANCE THEDLL = LoadLibrary("C:\\dllFolder\\theDll.dll");
  typedef float (*quxType)(void);
  quxType qux = (quxType)GetProcAddress(THEDLL, "quxMangledName");
  </code></pre>
  
  <p>So those are not a problem. </p>
  
  <p><strong>Now</strong>, the third on the list looks like another function that takes void, but it doesn't have an explicit return type. Does this mean I should just use an implicit type for it, is it void, or is it not really a function? If not, what is it?</p>
  
  <p>I have no idea what to do with the fourth one. Is it even possible to handle without the associated .h file?</p>
  
  <p>I looked around, but I couldn't find any information on what to do when the function doesn't look like a normal function with an explicit return type. Despite using basically the same code that I used to get a function working in a similar .dll, I keep getting an access violation crash when I try to use function #2 here (I really just need function #2). So I am guessing that the .dll needs more information or needs something initialized first, which is why I am interested in the others on the list.</p>
  
  <p>I realize this is a complicated problem, so there probably won't be a "Right answer" solution to get it working, but if I am making any obvious mistakes, or if there are any general suggestions for how to attack the problem (even alternatives to dependency walker), let me know.</p>
