title: Correct way to export a DLL function on Mac OSX
body: <p>I'm trying to compile a simple DLL on a Mac OS X 10.6, and am confused about the proper way to declare a function that the DLL offers up for the world to use.   Following sample code from a reliable source, I came up with:</p>
  
  <pre><code>__declspsec(dllexport) pascal int ReturnTheNumberFive(void)
  </code></pre>
  
  <p>but gcc barfs on it.   What the sample code actually had was MACPASCAL and DLLExport, which I assumed were macros.  I grepped through the sample codes, SDKs, etc for #defines and plugged in what I found.   These definitions could have been buried inside #ifs, so what I found isn't good and true.  Illogically, the compiler also barfs if I just do the obvious and use DLLExport and MACPASCAL, so that's no solution.</p>
  
  <p>What is the correct way to make a DLL's function available to apps?  </p>
