If I have to comment :)
If you use a vlc_variable (like when using var_*) only for the
configuration (seems to be the case here as you don't register any
callback on the variables), that's better to use var_Inherit* instead of
var_CreateGet*. In fact the second method will create the variable,
inherit the value from the configuration and return it. The first one
will just inherit the value from the configuration and return it.
That's a bit faster and uses a bit less memory. There is not a huge
difference but it doesn't cost anything.
