Hi to one and all,
Is there a way, by inspecting exif info, to know if a picture
(at night time) is under-exposed ? Is the fact that the shutter
speed seems to be set to the slowest case indicates that
we are under exposed?

No, it's all a matter of what you think looks right, the exif will say
nothing. The histogram on the LCD (if available) will give useful info
though and you can check the histogram on a file in photoshop or other
software.

Really? That seems awfully complicated.

My camera lets out a little sigh whenever the shot is underexposed, so
as long as you listen carefully, it's quite easy to tell.

Heh

Well there is the little blinky thing in the viewfinder too but I tend
to ignore all that. It would be nice if it said things to me like "you
moron, you forgot & left the ISO at 800 & this is full daylight" or
"It's going to look blurry at this speed, Paul"

I look at the histogram and decide for myself.

I usually look at the picture, and if it looks too dark, it's a good
indicator that it's under-exposed. YMMV.
