That Windows temporary directory that you've always been looking for

Use the following snippet to obtain the executing computer's temporary directory:

    str dirTmp = (isRunningOnServer() ? 
        WinAPIServer::getTempPath() : WinAPI::getTempPath());
    ;
    info(dirTmp);   // 'C:\Docs and Stuff\JDoe\Local Config\Temp\'

However... We're actually doing a bit more work inside that WinAPIServer::getTempPath() function as we're checking server-side for I/O access and dll interop permission so don't be surprised if you generate and error the first time you run it. Here's my call stack with the error:

Error en la solicitud de permiso de tipo 'FileIOPermission'.

The answer was in this post, indicating that we now need to assert 'FileIOPermission' before calling WinAPIServer::getTempPath()... Which personally feels wrong to me. I added the following hack before the call:

    FileIOPermission    _permHACK = new FileIOPermission('','r');
    str                 tempPath;                           
    ;
    _permHACK.assert();
    tempPath = (isRunningOnServer() ? 
        WinAPIServer::getTempPath() :WinAPI::getTempPath());
    // revert previous assertion
    CodeAccessPermission::revertAssert();

Later on in the code when obtaining read/write permission to the aforementioned temporary directory I was getting 'Varias llamadas a CodeAccessPermission.Assert/Multiple calls to CodeAccessPermission.Assert' error so don't forget to add the last line above, and revert our assertions before performing a second Assert. The alternative being to create a Set of these permission classes and assert multiple times.
