 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<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 264 Otherwise, if an item is reserved, the transfer fails.
 265
 266 C<$trigger> is the enum value for what triggered the transfer.
 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.

2177 setting C<returndate> to the current date.

2904
2905 Renews a loan.
2906
2907 C<$borrowernumber> is the borrower number of the patron who currently
2908 has the item.
2909
2910 C<$itemnumber> is the number of the item to renew.
2911
2912 C<$branch> is the library where the renewal took place (if any).
2913            The library that controls the circ policies for the renewal is retrieved from the issues record.
2914
2915 C<$datedue> can be a DateTime object used to set the due date.
2916
2917 C<$lastreneweddate> is an optional ISO-formatted date used to set issues.lastreneweddate.  If
2918 this parameter is not supplied, lastreneweddate is set to the current date.
2919
2920 C<$skipfinecalc> is an optional boolean. There may be circumstances where, even if the
2921 CalculateFinesOnReturn syspref is enabled, we don't want to calculate fines upon renew,
2922 for example, when we're renewing as a result of a fine being paid (see RenewAccruingItemWhenPaid
2923 syspref)
2924
2925 If C<$datedue> is the empty string, C<&AddRenewal> will calculate the due date automatically
2926 from the book's item type.
