 138 =head1 NAME
 139
 140 C4::Circulation - Koha circulation module
 141
 142 =head1 SYNOPSIS
 143
 144 use C4::Circulation;
 145
 146 =head1 DESCRIPTION
 147
 148 The functions in this module deal with circulation, issues, and
 149 returns, as well as general information about the library.
 150 Also deals with inventory.
 151
 152 =head1 FUNCTIONS
 153
 154 =head2 barcodedecode
 155
 156   $str = &barcodedecode($barcode, [$filter]);
 157
 158 Generic filter function for barcode string.
 159 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 160 Will do some manipulation of the barcode for systems that deliver a barcode
 161 to circulation.pl that differs from the barcode stored for the item.
 162 For proper functioning of this filter, calling the function on the
 163 correct barcode string (items.barcode) should return an unaltered barcode.
 164
 165 The optional $filter argument is to allow for testing or explicit
 166 behavior that ignores the System Pref.  Valid values are the same as the
 167 System Pref options.

 258
 259 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 260
 261 C<$newbranch> is the code for the branch to which the item should be transferred.
 262
 263 C<$barcode> is the barcode of the item to be transferred.
 264
 265 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 266 Otherwise, if an item is reserved, the transfer fails.
 267
 268 Returns three values:
 269
 270 =over
 271
 272 =item $dotransfer
 273
 274 is true if the transfer was successful.
 275
 276 =item $messages
 277
 278 is a reference-to-hash which may have any of the following keys:
 279
 280 =over
 281
 282 =item C<BadBarcode>
 283
 284 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 285
 286 =item C<DestinationEqualsHolding>
 287
 288 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.
 289
 290 =item C<WasReturned>
 291
 292 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.
 293
 294 =item C<ResFound>
 295
 296 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>.
 297
 298 =item C<WasTransferred>
 299
 300 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1271 Calculated if empty.

1285           * RESERVE PLACED ?
1286               - fill reserve if reserve to this patron

1288           * TRANSFERT PENDING ?

2617 C<$borrowernumber> is the borrower number of the patron who currently
2618 has the item on loan.
2619
2620 C<$itemnumber> is the number of the item to renew.

2622 C<$override_limit>, if supplied with a true value, causes
2623 the limit on the number of times that the loan can be renewed
2624 (as controlled by the item type) to be ignored. Overriding also allows
2625 to renew sooner than "No renewal before" and to manually renew loans
2626 that are automatically renewed.
2627
2628 C<$CanBookBeRenewed> returns a true value if the item may be renewed. The
2629 item must currently be on loan to the specified borrower; renewals
2630 must be allowed for the item's type; and the borrower must not have
2631 already renewed the loan. $error will contain the reason the renewal can not proceed
