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

 255
 256 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 257
 258 C<$newbranch> is the code for the branch to which the item should be transferred.
 259
 260 C<$barcode> is the barcode of the item to be transferred.
 261
 262 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 263 Otherwise, if an item is reserved, the transfer fails.
 264
 265 Returns three values:
 266
 267 =over
 268
 269 =item $dotransfer
 270
 271 is true if the transfer was successful.
 272
 273 =item $messages
 274
 275 is a reference-to-hash which may have any of the following keys:
 276
 277 =over
 278
 279 =item C<BadBarcode>
 280
 281 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 282
 283 =item C<DestinationEqualsHolding>
 284
 285 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.
 286
 287 =item C<WasReturned>
 288
 289 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.
 290
 291 =item C<ResFound>
 292
 293 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>.
 294
 295 =item C<WasTransferred>
 296
 297 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

2167   MarkIssueReturned($borrowernumber, $itemnumber, $returndate, $privacy);
2168
2169 Unconditionally marks an issue as being returned by
2170 moving the C<issues> row to C<old_issues> and
2171 setting C<returndate> to the current date.
2172
2173 if C<$returndate> is specified (in iso format), it is used as the date
2174 of the return.
2175
2176 C<$privacy> contains the privacy parameter. If the patron has set privacy to 2,
2177 the old_issue is immediately anonymised
2178
2179 Ideally, this function would be internal to C<C4::Circulation>,
2180 not exported, but it is currently used in misc/cronjobs/longoverdue.pl
2181 and offline_circ/process_koc.pl.

2895   &AddRenewal($borrowernumber, $itemnumber, $branch, [$datedue], [$lastreneweddate]);
2896
2897 Renews a loan.
2898
2899 C<$borrowernumber> is the borrower number of the patron who currently
2900 has the item.
2901
2902 C<$itemnumber> is the number of the item to renew.
2903
2904 C<$branch> is the library where the renewal took place (if any).
2905            The library that controls the circ policies for the renewal is retrieved from the issues record.
2906
2907 C<$datedue> can be a DateTime object used to set the due date.
2908
2909 C<$lastreneweddate> is an optional ISO-formatted date used to set issues.lastreneweddate.  If
2910 this parameter is not supplied, lastreneweddate is set to the current date.
2911
2912 C<$skipfinecalc> is an optional boolean. There may be circumstances where, even if the
2913 CalculateFinesOnReturn syspref is enabled, we don't want to calculate fines upon renew,
2914 for example, when we're renewing as a result of a fine being paid (see RenewAccruingItemWhenPaid
2915 syspref)
2916
2917 If C<$datedue> is the empty string, C<&AddRenewal> will calculate the due date automatically
2918 from the book's item type.
