 117 =head1 NAME
 118
 119 C4::Circulation - Koha circulation module
 120
 121 =head1 SYNOPSIS
 122
 123 use C4::Circulation;
 124
 125 =head1 DESCRIPTION
 126
 127 The functions in this module deal with circulation, issues, and
 128 returns, as well as general information about the library.
 129 Also deals with stocktaking.
 130
 131 =head1 FUNCTIONS
 132
 133 =head2 barcodedecode
 134
 135   $str = &barcodedecode($barcode, [$filter]);
 136
 137 Generic filter function for barcode string.
 138 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 139 Will do some manipulation of the barcode for systems that deliver a barcode
 140 to circulation.pl that differs from the barcode stored for the item.
 141 For proper functioning of this filter, calling the function on the
 142 correct barcode string (items.barcode) should return an unaltered barcode.
 143
 144 The optional $filter argument is to allow for testing or explicit
 145 behavior that ignores the System Pref.  Valid values are the same as the
 146 System Pref options.

 237
 238 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 239
 240 C<$newbranch> is the code for the branch to which the item should be transferred.
 241
 242 C<$barcode> is the barcode of the item to be transferred.
 243
 244 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 245 Otherwise, if an item is reserved, the transfer fails.
 246
 247 Returns three values:
 248
 249 =over
 250
 251 =item $dotransfer
 252
 253 is true if the transfer was successful.
 254
 255 =item $messages
 256
 257 is a reference-to-hash which may have any of the following keys:
 258
 259 =over
 260
 261 =item C<BadBarcode>
 262
 263 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 264
 265 =item C<IsPermanent>
 266
 267 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.
 268
 269 =item C<DestinationEqualsHolding>
 270
 271 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.
 272
 273 =item C<WasReturned>
 274
 275 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.
 276
 277 =item C<ResFound>
 278
 279 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>.
 280
 281 =item C<WasTransferred>
 282
 283 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1568 C<&AddReturn> returns a list of four items:
1569
1570 C<$doreturn> is true iff the return succeeded.
1571
1572 C<$messages> is a reference-to-hash giving feedback on the operation.
1573 The keys of the hash are:
1574
1575 =over 4
1576
1577 =item C<BadBarcode>
1578
1579 No item with this barcode exists. The value is C<$barcode>.
1580
1581 =item C<NotIssued>
1582
1583 The book is not currently on loan. The value is C<$barcode>.
1584
1585 =item C<IsPermanent>
1586
1587 The book's home branch is a permanent collection. If you have borrowed
1588 this book, you are not allowed to return it. The value is the code for
1589 the book's home branch.
1590
1591 =item C<wthdrawn>
1592
1593 This book has been withdrawn/cancelled. The value should be ignored.
1594
1595 =item C<Wrongbranch>
1596
1597 This book has was returned to the wrong branch.  The value is a hashref
1598 so that C<$messages->{Wrongbranch}->{Wrongbranch}> and C<$messages->{Wrongbranch}->{Rightbranch}>
1599 contain the branchcode of the incorrect and correct return library, respectively.
1600
1601 =item C<ResFound>
1602
1603 The item was reserved. The value is a reference-to-hash whose keys are
1604 fields from the reserves table of the Koha database, and
1605 C<biblioitemnumber>. It also has the key C<ResFound>, whose value is
1606 either C<Waiting>, C<Reserved>, or 0.
1607
1608 =back
1609
1610 C<$iteminformation> is a reference-to-hash, giving information about the
1611 returned item from the issues table.
1612
1613 C<$borrower> is a reference-to-hash, giving information about the
1614 patron who last borrowed the book.

2336 C<$dbh> is a DBI handle to the Koha database.
2337
2338 C<$borrowernumber> is the borrower number of the patron who currently
2339 has the item on loan.
2340
2341 C<$itemnumber> is the number of the item to renew.
2342
2343 C<$override_limit>, if supplied with a true value, causes
2344 the limit on the number of times that the loan can be renewed
2345 (as controlled by the item type) to be ignored.
2346
2347 C<$CanBookBeRenewed> returns a true value iff the item may be renewed. The
2348 item must currently be on loan to the specified borrower; renewals
2349 must be allowed for the item's type; and the borrower must not have
2350 already renewed the loan. $error will contain the reason the renewal can not proceed
