Detect if binary file (exe or DLL) is 32 or 64bits

Hi,

I have added a new category in the forum, called "coding tips" to share any code, or functions that might be useful for LuaRT users. Here you will find a simple Lua function to detect wether the provided binary filename (as a string) is for 32bits or 64bits platform :

function getBinaryType(file)
    local f = tostring(sys.File(file):open("read", "binary"):read())
    if f:find("PE\0\0\x64\x86") then
        return "x64"
    else
        return "x86"
    end
end
