 136 =head1 NAME
 137
 138 C4::Circulation - Koha circulation module
 139
 140 =head1 SYNOPSIS
 141
 142 use C4::Circulation;
 143
 144 =head1 DESCRIPTION
 145
 146 The functions in this module deal with circulation, issues, and
 147 returns, as well as general information about the library.
 148 Also deals with inventory.
 149
 150 =head1 FUNCTIONS
 151
 152 =head2 barcodedecode
 153
 154   $str = &barcodedecode($barcode, [$filter]);
 155
 156 Generic filter function for barcode string.
 157 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 158 Will do some manipulation of the barcode for systems that deliver a barcode
 159 to circulation.pl that differs from the barcode stored for the item.
 160 For proper functioning of this filter, calling the function on the
 161 correct barcode string (items.barcode) should return an unaltered barcode.
 162
 163 The optional $filter argument is to allow for testing or explicit
 164 behavior that ignores the System Pref.  Valid values are the same as the
 165 System Pref options.

 256
 257 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 258
 259 C<$newbranch> is the code for the branch to which the item should be transferred.
 260
 261 C<$barcode> is the barcode of the item to be transferred.
 262
 263 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 264 Otherwise, if an item is reserved, the transfer fails.
 265
 266 Returns three values:
 267
 268 =over
 269
 270 =item $dotransfer
 271
 272 is true if the transfer was successful.
 273
 274 =item $messages
 275
 276 is a reference-to-hash which may have any of the following keys:
 277
 278 =over
 279
 280 =item C<BadBarcode>
 281
 282 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 283
 284 =item C<DestinationEqualsHolding>
 285
 286 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.
 287
 288 =item C<WasReturned>
 289
 290 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.
 291
 292 =item C<ResFound>
 293
 294 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>.
 295
 296 =item C<WasTransferred>
 297
 298 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

2650
2651 C<$itemnumber> is the number of the item to renew.

2653 C<$override_limit>, if supplied with a true value, causes
2654 the limit on the number of times that the loan can be renewed
2655 (as controlled by the item type) to be ignored. Overriding also allows
2656 to renew sooner than "No renewal before" and to manually renew loans
2657 that are automatically renewed.
2658
2659 C<$CanBookBeRenewed> returns a true value if the item may be renewed. The
2660 item must currently be on loan to the specified borrower; renewals
2661 must be allowed for the item's type; and the borrower must not have
2662 already renewed the loan. $error will contain the reason the renewal can not proceed
