Hi, on a 64 bit Windows machine os.uname() erroneously returns

machine i686

On the same machine I get under Linux

machine x86_64

with both, x86_64-linux and i386-linux binaries. Thus I assume that the keyword 'machine' refers to the hardware, not to how the binaries were compiled (32 vs. 64 bit).

The complete output of

for k,v in pairs(os.uname()) do print(k,v) end

is

release build 9200 nodename R804 version 6.02 machine i686 sysname Windows 8

#ifdef _WIN32 # define _UTSNAME_LENGTH 65

/* Structure describing the system and machine. */ struct utsname { char sysname[_UTSNAME_LENGTH]; char nodename[_UTSNAME_LENGTH]; char release[_UTSNAME_LENGTH]; char version[_UTSNAME_LENGTH]; char machine[_UTSNAME_LENGTH]; };

/* * Get name and information about current kernel. */ static int uname(struct utsname *uts) :

case WinNT: sprintf(uts->machine, "i%d86", sysinfo.wProcessorLevel); break;

I guess that wProcessorLevel gives 6 in your case.

Obviously. But I doubt that wProcessorLevel is what's needed here. Isn't there something like wProcessorArchitecture that distinguishes between 32 and 64 bit?
