Host Operating System?

Hi,

Is there a cross-platform way of identifying the host operating system that your code is running upon?

I've been using this, but need a little more detail to identify distribution/version (XP, Win7, Win8, Ubuntu, Debian, Mint etc) to include in fault reporting and OS-specific code.

global platform$ = ""
?win32
	platform = "windows"
?macos
	platform = "mac"
?linux
	platform = "linux"
?

Cheers in advance...

I have code in the code archives to determine the Windows version. I haven't updated it for Windows 8 but I'm sure you can modify it.

Any idea how Windows 8.1 identifies itself?
I'm assuming 6.3?

GfK	(Posted 2013) [#4]

6.3 apparently. Which is odd, because I would have assumed it to be a minor revision of 6.2.

I've used the uname() function from utsname.h to create a linux equivalent but I am seeing a behaviour that is different from the docs.

utsname.h defines SYS_NAMELEN as 256:

#define	_SYS_NAMELEN	256

struct	utsname {
	char	sysname[_SYS_NAMELEN];	/* Name of OS */
	char	nodename[_SYS_NAMELEN];	/* Name of this network node */
	char	release[_SYS_NAMELEN];	/* Release level */
	char	version[_SYS_NAMELEN];	/* Version level */
	char	machine[_SYS_NAMELEN];	/* Hardware type */
};

But when I coded this it didn't work. After some investigation of the results it appears that SYS_NAMELEN should be 65!

SuperStrict
?linux
	'#include <sys/utsname.h>
	Global utsname:TBank = CreateBank( 1280 )
	Extern "c"
	Function uname:Int( struct: Byte Ptr )
	End Extern	
	Local result% = uname( utsname.buf() )
	If result = 0 Then
		Print "SYSTEM:   " + String.fromCString( utsname.buf() )
		Print "NODE:     " + String.fromCString( utsname.buf()+65 )
		Print "REVISION: " + String.fromCString( utsname.buf()+130 )
		Print "VERSION:  " + String.fromCString( utsname.buf()+195 )
		Print "MACHINE:  " + String.fromCString( utsname.buf()+260 )
		Print "DOMAIN:   " + String.fromCString( utsname.buf()+325 )
	End If
?

The above code prints the following:

SYSTEM:   Linux
NODE:     linuxmint
REVISION: 3.0.0-13-generic
VERSION:  #22-Ubuntu SMP Wed Nov 2 13:25:36 UTC 2011
MACHINE:  i686
DOMAIN:   (none)

Any suggestions why SYS_NAMELEN should be different?
