Running different codes for different systems

[luciano de souza <luchyanus@...>]

Hi all,

I wrote a code intended to be executed in windows and ubuntu. and I
used IUP as a graphical library. I am blind and with IUP, I can create
simple graphical interfaces compatible with screen readers.

Since screen readers works differently in Windows and Linux, I need to
insert a code regarding the running operational system.

if {command to identify windows} == true then
{commands applied to Windows system}
else
{command applied to Linux system}
end

I imagined I would get it with a command like "os.getenv('system') ==
'windows'", but there is no a environment variable called 'system'.

What do you suggest?

Regards,

Luciano
