Bitness of the system on Vala

Question

As for the Vala language cross-platform to know the bitness of the system?

@JensMühlenhoff You will need to download the files you are using, depending on the bitness of the system. — Syabro, Mar 12 '18 at 03:41
I see, that is one of the rare cases where it would be useful indeed. — Jens Mühlenhoff, Mar 12 '18 at 09:21

sizeof(void*) will be 8 for 64-bit systems and 4 for 32 bit systems. Also, 2 for 16 bit systems, but I don't even know that glib will work there.

Thanks. And in Glib there is no more aesthetic way? – Syabro Mar 12 '18 at 03:42

The whole point of GLib is to avoid having to do platform specific code.

However according to you comment you want to do something like download platform specific packages.

First of all it would be better to use a system or user package manager to do that, since they already know how to achieve that (DRY principle).

If you absolutely must, you can also use tools like lsb-release -a or the more general uname -a (for the kernel and arch) or some other arguments to those tools.

You can invoke them with GLibs process spawning facilities.
