 122 =head1 NAME
 123
 124 C4::Circulation - Koha circulation module
 125
 126 =head1 SYNOPSIS
 127
 128 use C4::Circulation;
 129
 130 =head1 DESCRIPTION
 131
 132 The functions in this module deal with circulation, issues, and
 133 returns, as well as general information about the library.
 134 Also deals with stocktaking.
 135
 136 =head1 FUNCTIONS
 137
 138 =head2 barcodedecode
 139
 140   $str = &barcodedecode($barcode, [$filter]);
 141
 142 Generic filter function for barcode string.
 143 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 144 Will do some manipulation of the barcode for systems that deliver a barcode
 145 to circulation.pl that differs from the barcode stored for the item.
 146 For proper functioning of this filter, calling the function on the
 147 correct barcode string (items.barcode) should return an unaltered barcode.
 148
 149 The optional $filter argument is to allow for testing or explicit
 150 behavior that ignores the System Pref.  Valid values are the same as the
 151 System Pref options.

 242
 243 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 244
 245 C<$newbranch> is the code for the branch to which the item should be transferred.
 246
 247 C<$barcode> is the barcode of the item to be transferred.
 248
 249 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 250 Otherwise, if an item is reserved, the transfer fails.
 251
 252 Returns three values:
 253
 254 =over
 255
 256 =item $dotransfer
 257
 258 is true if the transfer was successful.
 259
 260 =item $messages
 261
 262 is a reference-to-hash which may have any of the following keys:
 263
 264 =over
 265
 266 =item C<BadBarcode>
 267
 268 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 269
 270 =item C<IsPermanent>
 271
 272 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.
 273
 274 =item C<DestinationEqualsHolding>
 275
 276 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.
 277
 278 =item C<WasReturned>
 279
 280 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.
 281
 282 =item C<ResFound>
 283
 284 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>.
 285
 286 =item C<WasTransferred>
 287
 288 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1944   MarkIssueReturned($borrowernumber, $itemnumber, $dropbox_branch, $returndate, $privacy);
1945
1946 Unconditionally marks an issue as being returned by
1947 moving the C<issues> row to C<old_issues> and
1948 setting C<returndate> to the current date, or
1949 the last non-holiday date of the branccode specified in
1950 C<dropbox_branch> .  Assumes you've already checked that
1951 it's safe to do this, i.e. last non-holiday > issuedate.
1952
1953 if C<$returndate> is specified (in iso format), it is used as the date
1954 of the return. It is ignored when a dropbox_branch is passed in.
1955
1956 C<$privacy> contains the privacy parameter. If the patron has set privacy to 2,
1957 the old_issue is immediately anonymised
1958
1959 Ideally, this function would be internal to C<C4::Circulation>,
1960 not exported, but it is currently needed by one
1961 routine in C<C4::Accounts>.
