creating a function that works for active region or whole buffer |

Hi all,
I'd like to write a function that can be invoked when a region is
active, and therefore is limited to the region itself, or on the whole
buffer if not any region is active. Therefore in my function I placed
the following conditional to set the start-block and end-block lines
to the whole buffer or the whole region:
(if (not (null (region-beginning) ) )
(progn
(setq current-block-start-line (line-number-at-pos
(region-beginning) ) )
(setq current-block-end-line (line-number-at-pos
(region-end) ) ) )
; else mark the whole buffer
(progn
(setq current-block-start-line (line-number-at-pos (point-min) ) )
(setq current-block-end-line (line-number-at-pos (point-max) ) ) ) )
It seems to work, but when I mark a region, that remove the region
(i.e., unmark) and call the function again it seems that the function
has still the region-beginning and region-end marks (i.e., it does not
work on the whole buffer). Is there a smarter way to see if a region
is currently active?
Thanks,
Luca
