 124 =head1 NAME
 125
 126 C4::Circulation - Koha circulation module
 127
 128 =head1 SYNOPSIS
 129
 130 use C4::Circulation;
 131
 132 =head1 DESCRIPTION
 133
 134 The functions in this module deal with circulation, issues, and
 135 returns, as well as general information about the library.
 136 Also deals with stocktaking.
 137
 138 =head1 FUNCTIONS
 139
 140 =head2 barcodedecode
 141
 142   $str = &barcodedecode($barcode, [$filter]);
 143
 144 Generic filter function for barcode string.
 145 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 146 Will do some manipulation of the barcode for systems that deliver a barcode
 147 to circulation.pl that differs from the barcode stored for the item.
 148 For proper functioning of this filter, calling the function on the
 149 correct barcode string (items.barcode) should return an unaltered barcode.
 150
 151 The optional $filter argument is to allow for testing or explicit
 152 behavior that ignores the System Pref.  Valid values are the same as the
 153 System Pref options.

 244
 245 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 246
 247 C<$newbranch> is the code for the branch to which the item should be transferred.
 248
 249 C<$barcode> is the barcode of the item to be transferred.
 250
 251 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 252 Otherwise, if an item is reserved, the transfer fails.
 253
 254 Returns three values:
 255
 256 =over
 257
 258 =item $dotransfer
 259
 260 is true if the transfer was successful.
 261
 262 =item $messages
 263
 264 is a reference-to-hash which may have any of the following keys:
 265
 266 =over
 267
 268 =item C<BadBarcode>
 269
 270 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 271
 272 =item C<IsPermanent>
 273
 274 The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
 275
 276 =item C<DestinationEqualsHolding>
 277
 278 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.
 279
 280 =item C<WasReturned>
 281
 282 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.
 283
 284 =item C<ResFound>
 285
 286 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>.
 287
 288 =item C<WasTransferred>
 289
 290 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1957
1958 Unconditionally marks an issue as being returned by
1959 moving the C<issues> row to C<old_issues> and
1960 setting C<returndate> to the current date, or
1961 the last non-holiday date of the branccode specified in
1962 C<dropbox_branch> .  Assumes you've already checked that
1963 it's safe to do this, i.e. last non-holiday > issuedate.
1964
1965 if C<$returndate> is specified (in iso format), it is used as the date
1966 of the return. It is ignored when a dropbox_branch is passed in.
1967
1968 C<$privacy> contains the privacy parameter. If the patron has set privacy to 2,
1969 the old_issue is immediately anonymised
