back-bdb and IDL

[Pierangelo Masarati <masarati@aero.polimi.it>]

Kurt,

I'm digging into back-bdb; I'd like to know what's the more
appropriate (and the likely not to change very soon) way
to determine the number of candidates are returned by  
search_candidates(); at a first glance 

(BDB_IDL_IS_RANGE( candidates ) ? candidates[2] :
candidates[candidates[0]])-candidates[1]+1

Is this correct and reliable? Is there a macro that does 
the same?

Pierangelo.
