 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.

 261
 262 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 263
 264 C<$fbr> is the code for the branch initiating the transfer.
 265 C<$tbr> is the code for the branch to which the item should be transferred.
 266
 267 C<$barcode> is the barcode of the item to be transferred.
 268
 269 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 270 Otherwise, if an item is reserved, the transfer fails.
 271
 272 C<$trigger> is the enum value for what triggered the transfer.
 273
 274 Returns three values:
 275
 276 =over
 277
 278 =item $dotransfer
 279
 280 is true if the transfer was successful.
 281
 282 =item $messages
 283
 284 is a reference-to-hash which may have any of the following keys:
 285
 286 =over
 287
 288 =item C<BadBarcode>
 289
 290 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 291
 292 =item C<DestinationEqualsHolding>
 293
 294 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.
 295
 296 =item C<WasReturned>
 297
 298 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.
 299
 300 =item C<ResFound>
 301
 302 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>.
 303
 304 =item C<WasTransferred>
 305
 306 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

2940 C<$borrowernumber> is the borrower number of the patron who currently
2941 has the item.
2942
2943 C<$itemnumber> is the number of the item to renew.
2944
2945 C<$branch> is the library where the renewal took place (if any).
2946            The library that controls the circ policies for the renewal is retrieved from the issues record.
2947
2948 C<$datedue> can be a DateTime object used to set the due date.
2949
2950 C<$lastreneweddate> is an optional ISO-formatted date used to set issues.lastreneweddate.  If
2951 this parameter is not supplied, lastreneweddate is set to the current date.
2952
2953 C<$skipfinecalc> is an optional boolean. There may be circumstances where, even if the
2954 CalculateFinesOnReturn syspref is enabled, we don't want to calculate fines upon renew,
2955 for example, when we're renewing as a result of a fine being paid (see RenewAccruingItemWhenPaid
2956 syspref)
2957
2958 If C<$datedue> is the empty string, C<&AddRenewal> will calculate the due date automatically
