  56 =head1 DESCRIPTION
  57
  58 The functions in this module deal with circulation, issues, and

 170 =head2 transferbook
 171
 172 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
 173
 174 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 175
 176 C<$newbranch> is the code for the branch to which the item should be transferred.
 177
 178 C<$barcode> is the barcode of the item to be transferred.
 179
 180 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 181 Otherwise, if an item is reserved, the transfer fails.
 182
 183 Returns three values:
 184
 185 =head3 $dotransfer
 186
 187 is true if the transfer was successful.
 188
 189 =head3 $messages
 190
 191 is a reference-to-hash which may have any of the following keys:
 192
 193 =over 4
 194
 195 =item C<BadBarcode>
 196
 197 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 198
 199 =item C<IsPermanent>
 200
 201 The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
 202
 203 =item C<DestinationEqualsHolding>
 204
 205 The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored.
 206
 207 =item C<WasReturned>
 208
 209 The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item.
 210
 211 =item C<ResFound>
 212
 213 The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>.
 214
 215 =item C<WasTransferred>
 216
 217 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.
