Summary: cscoreListExtractTime always returns an empty list

Initial Comment:
cscoreListExtractTime always returns an empty list.
Fix: followed each call to cscoreCopyEvent with the statement: "b->nevents++;" This will reveal a range bug, which can be fixed by replacing the "(e->p[2] < to)" test with "((e->p[2] >= from) && (e->p[2] < to))".

Message:
I think I understand now; you refer to calls in the function
cscoreListExtractTime only.

I have understood the changes and made them, but it still looks like wrng
answer.  I now get 1, but surely I should have 2?

Message:
Thank you, but I still do not understabd your fix.  What is b?  Every call
or every call in some function?  If every call then why is it not in the
function?

I am still not sure how to run your example

void cscore(CSOUND *cs) 
{ 
    EVLIST *a = cscoreListGetSection(cs);
    EVLIST *b = cscoreListExtractTime(cs, a, FL(1.0), FL(3.0));
    printf("%d\n", cscoreListCount(cs, b)); // this always prints '0'
}

i1  0  1      1
i1  1  1      2
i1  2  1      3

Please can you supply either a test program, or a fixed source file, or
both?  I am having trouble understanding both the error and the fix
