 129 =head1 NAME
 130
 131 C4::Circulation - Koha circulation module
 132
 133 =head1 SYNOPSIS
 134
 135 use C4::Circulation;
 136
 137 =head1 DESCRIPTION
 138
 139 The functions in this module deal with circulation, issues, and
 140 returns, as well as general information about the library.
 141 Also deals with stocktaking.
 142
 143 =head1 FUNCTIONS
 144
 145 =head2 barcodedecode
 146
 147   $str = &barcodedecode($barcode, [$filter]);
 148
 149 Generic filter function for barcode string.
 150 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 151 Will do some manipulation of the barcode for systems that deliver a barcode
 152 to circulation.pl that differs from the barcode stored for the item.
 153 For proper functioning of this filter, calling the function on the
 154 correct barcode string (items.barcode) should return an unaltered barcode.
 155
 156 The optional $filter argument is to allow for testing or explicit
 157 behavior that ignores the System Pref.  Valid values are the same as the
 158 System Pref options.

 249
 250 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 251
 252 C<$newbranch> is the code for the branch to which the item should be transferred.
 253
 254 C<$barcode> is the barcode of the item to be transferred.
 255
 256 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 257 Otherwise, if an item is reserved, the transfer fails.
 258
 259 Returns three values:
 260
 261 =over
 262
 263 =item $dotransfer
 264
 265 is true if the transfer was successful.
 266
 267 =item $messages
 268
 269 is a reference-to-hash which may have any of the following keys:
 270
 271 =over
 272
 273 =item C<BadBarcode>
 274
 275 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 276
 277 =item C<IsPermanent>
 278
 279 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.
 280
 281 =item C<DestinationEqualsHolding>
 282
 283 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.
 284
 285 =item C<WasReturned>
 286
 287 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.
 288
 289 =item C<ResFound>
 290
 291 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>.
 292
 293 =item C<WasTransferred>
 294
 295 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

2060 the last non-holiday date of the branccode specified in
