[sword-devel] Counting Keys in a Module

Thanks for the reply. Very much appreciated. Mr. Smith's method seems to be very neat and I will try to implement that. I needed the count method because a virtual List Control that displays the lexicon needs to know number of entries in advance.
Right now I am getting the count using a slightly improved brute force:

int GetNumEntries()

// initial guess

int high = 10000, low = 0, mid = (high + low)/2;

while ( high - low > 1 ) {

pModule->setPosition(sword::TOP);   pModule->increment(mid);

if( pModule->Error() )     high = mid;

else low = mid;

mid = (high + low)/2; 


return high;


I am not sure what are the dangers in doing this (if any).
