[Mono-osx] OSX vs Linux

[Gavin Landon]

LoL..  A coworker and I was talking about how else it was possible and
had mentioned going to the file level.  That's funny.

Thanks

Currently we use the following function (note C Sharp code)

        //
---------------------------------------------------------------
        static private string getMachineType()
        {
            string ret = "unknown";
            switch (Environment.OSVersion.Platform) {
            case PlatformID.Unix:
                ret = "Unix";
                // need to execute uname -s to find out if it is a MAC
or not
                StringBuilder output = new StringBuilder();
                int nRet = execute("uname -s", output);
                if ((nRet == 0) &&
(output.ToString().StartsWith("Darwin"))) {
                    ret = "Mac";
                } // end if
                break;
            case PlatformID.Win32NT:
                ret = "WinNT";
                break;
            case PlatformID.Win32S:
                ret = "Win32s";
                break;
            case PlatformID.Win32Windows:
                ret = "Win95+";
                break;
            case PlatformID.WinCE:
                ret = "WinCE";
                break;
            } // end switch

            return ret;
        } // end getMachineType


Where the execute call is 

        //
---------------------------------------------------------------
        static public int execute(string _command, StringBuilder
_output)
        {
            int ret = -1;

            Process proc = new Process();
            int firstSpaceIndex = _command.IndexOf(' ');
            string command = _command.Substring(0, firstSpaceIndex);
            string commandLine = _command.Substring(firstSpaceIndex);
            proc.StartInfo.FileName = command;
            proc.StartInfo.Arguments = commandLine;
            proc.StartInfo.UseShellExecute = false;
            proc.StartInfo.CreateNoWindow = true;

            // redirect output if we want to
            ms_output = _output;
            proc.StartInfo.RedirectStandardError = true;
            proc.StartInfo.RedirectStandardOutput = true;
            proc.OutputDataReceived += new
DataReceivedEventHandler(outputDataReceived_static);
            proc.ErrorDataReceived += new
DataReceivedEventHandler(errorDataReceived_static);

            try {
                proc.Start();
                proc.BeginErrorReadLine();
                proc.BeginOutputReadLine();
                proc.WaitForExit();
                ret = proc.ExitCode;
                proc.Close();
            } // end try
            catch (Exception _e) {
                if (_output != null) {
                    _output.AppendFormat("Exception \"{0}\"\nfor {2}
{3}\nStack Trace{1}", _e.Message, _e.StackTrace, command, commandLine);
                } // end if
                ret = -1;
            } // end catch
            ms_output = null;

            return ret;
        } // end execute

        //
---------------------------------------------------------------
        static void errorDataReceived_static(object sender,
DataReceivedEventArgs e)
        {
            if (!String.IsNullOrEmpty(e.Data)) {
                if (ms_output != null) {
                    ms_output.AppendFormat("{0}{1}", e.Data,
Environment.NewLine);
                } // end if
            } // end if
        }

        //
---------------------------------------------------------------
        static void outputDataReceived_static(object sender,
DataReceivedEventArgs e)
        {
            if (!String.IsNullOrEmpty(e.Data)) {
                if (ms_output != null) {
                    ms_output.AppendFormat("{0}{1}", e.Data,
Environment.NewLine);
                } // end if
            } // end if
        } // end execute

And this works for us... though it would fail on a non-MacOSX Darwin
machine... not too many of them I think.

Well, the only thing I can come up with is looking at the version
itself.  Of course this method will have be changed and the Major bumped
up as Linux catches up..
------------------
static public string GetOS()
{
	int p = (int) Environment.OSVersion.Platform;
	int v = (int) Environment.OSVersion.Version.Major;
	
	if(Environment.OSVersion.Platform.ToString()=="Win32NT")
		return "Windows";
	
        if ((p == 4) || (p == 128)) {
		if(v<8)
			return "Unix";
		else
			return "OSX";
	} 
	
	return "Unknown";
}

I'm having some trouble distinguishing the difference between Linux and
OSX.  

I have a test method I'm using to try different things out and both OSX
and Linux come back with "Unix" as the text and p="4".  The only
difference is OSVersion will return a much lower version number on Linux
that on Mac.  Is there another way to tell?

------------------
static public string GetOS()
{
	int p = (int) Environment.OSVersion.Platform;
	
	MessageBox.Show("Environment.OSVersion.Version: " +
Environment.OSVersion.Version.ToString());
	MessageBox.Show("Environment.OSVersion: " +
Environment.OSVersion.ToString());
	MessageBox.Show("OS Version: " +
Environment.OSVersion.Platform.ToString() + " #" + p.ToString());

	if(Environment.OSVersion.Platform.ToString()=="Win32NT")
		return "Windows";
        if ((p == 4) || (p == 128)) {
		return "Unix";
	} else {
        	return "Not Unix";
	}
}
