There is not such functionality implemented under Windows right now.
Unless I missed something.

"Primary" suit better than "main". This function return index of
primary display, one with task bar, icons etc. Under Windows that can
be any connected monitor, on other OS'es this is usually first one.
This function always valid index of primary adapter or -1 when there
are no adapter connected.

Active monitor is one on which you are working on. With multimonitor
system setup, new application window is created on monitor from which
you're launching application. That will happen unless you force OS do
to place window at very specific point. Current Windows implementation
always create window centered on the first available monitor by
default.
This function return valid index of active adapter or -1 if index
cannot be determined.

I think Allegro should be released this weekend. This is big fix which
include not only window creation but also fullscreen support (yap,
also broken on multi-monitor system). 5.1 is target for this fix. Two
days or even week is not enough to test new implementation properly.
