($count, $results) = &FindReserves($biblionumber, $borrowernumber);
Looks books up in the reserves. C<$biblionumber> is the biblionumber
of the book to look up. C<$borrowernumber> is the borrower number of a
patron whose books to look up.
Either C<$biblionumber> or C<$borrowernumber> may be the empty string,
but not both. If both are specified, C<&FindReserves> looks up the
given book for the given patron. If only C<$biblionumber> is
specified, C<&FindReserves> looks up that book for all patrons. If
only C<$borrowernumber> is specified, C<&FindReserves> looks up all of
that patron's reserves. If neither is specified, C<&FindReserves>
barfs.
For each book thus found, C<&FindReserves> checks the reserve
constraints and does something I don't understand.
C<&FindReserves> returns a two-element array:
C<$count> is the number of elements in C<$results>.
C<$results> is a reference-to-array; each element is a
reference-to-hash, whose keys are (I think) all of the fields of the
reserves, borrowers, and biblio tables of the Koha database.

=item CheckReserves
($status, $reserve) = &CheckReserves($itemnumber, $barcode);
Find a book in the reserves.
C<$itemnumber> is the book's item number. C<$barcode> is its barcode.
Either one, but not both, may be false. If both are specified,
C<&CheckReserves> uses C<$itemnumber>.
$itemnubmer can be false, in which case uses the barcode. (Never uses
both. $itemnumber gets priority).
As I understand it, C<&CheckReserves> looks for the given item in the
reserves. If it is found, that's a match, and C<$status> is set to
C<Waiting>.
Otherwise, it finds the most important item in the reserves with the
same biblio number as this book (I'm not clear on this) and returns it
with C<$status> set to C<Reserved>.
C<&CheckReserves> returns a two-element list:
C<$status> is either C<Waiting>, C<Reserved> (see above), or 0.
C<$reserve> is the reserve item that matched. It is a
reference-to-hash whose keys are mostly the fields of the reserves
table in the Koha database.

I don't know what this does, because I don't understand how reserve
constraints work. I think the idea is that you reserve a particular
biblio, and the constraint allows you to restrict it to a given
biblioitem (e.g., if you want to borrow the audio book edition of "The
Prophet", rather than the first available publication).
