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

 245
 246 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 247
 248 C<$newbranch> is the code for the branch to which the item should be transferred.
 249
 250 C<$barcode> is the barcode of the item to be transferred.
 251
 252 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 253 Otherwise, if an item is reserved, the transfer fails.
 254
 255 Returns three values:
 256
 257 =over
 258
 259 =item $dotransfer
 260
 261 is true if the transfer was successful.
 262
 263 =item $messages
 264
 265 is a reference-to-hash which may have any of the following keys:
 266
 267 =over
 268
 269 =item C<BadBarcode>
 270
 271 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 272
 273 =item C<IsPermanent>
 274
 275 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.
 276
 277 =item C<DestinationEqualsHolding>
 278
 279 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.
 280
 281 =item C<WasReturned>
 282
 283 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.
 284
 285 =item C<ResFound>
 286
 287 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>.
 288
 289 =item C<WasTransferred>
 290
 291 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1982
1983 Unconditionally marks an issue as being returned by
1984 moving the C<issues> row to C<old_issues> and
1985 setting C<returndate> to the current date, or
1986 the last non-holiday date of the branccode specified in
1987 C<dropbox_branch> .  Assumes you've already checked that
1988 it's safe to do this, i.e. last non-holiday > issuedate.
1989
1990 if C<$returndate> is specified (in iso format), it is used as the date
1991 of the return. It is ignored when a dropbox_branch is passed in.
1992
1993 C<$privacy> contains the privacy parameter. If the patron has set privacy to 2,
1994 the old_issue is immediately anonymised
1995
1996 Ideally, this function would be internal to C<C4::Circulation>,
1997 not exported, but it is currently needed by one
1998 routine in C<C4::Accounts>.
