 102 =head1 SYNOPSIS
 103
 104 use C4::Circulation;
 105
 106 =head1 DESCRIPTION
 107
 108 The functions in this module deal with circulation, issues, and
 109 returns, as well as general information about the library.
 110 Also deals with stocktaking.

 112 =head1 FUNCTIONS

 117
 118 =over 4
 119
 120 =item Generic filter function for barcode string.
 121 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 122 Will do some manipulation of the barcode for systems that deliver a barcode
 123 to circulation.pl that differs from the barcode stored for the item.
 124 For proper functioning of this filter, calling the function on the
 125 correct barcode string (items.barcode) should return an unaltered barcode.

 202 =head2 transferbook
 203
 204 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
 205
 206 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 207
 208 C<$newbranch> is the code for the branch to which the item should be transferred.
 209
 210 C<$barcode> is the barcode of the item to be transferred.
 211
 212 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 213 Otherwise, if an item is reserved, the transfer fails.
 214
 215 Returns three values:
 216
 217 =head3 $dotransfer
 218
 219 is true if the transfer was successful.
 220
 221 =head3 $messages
 222
 223 is a reference-to-hash which may have any of the following keys:
 224
 225 =over 4
 226
 227 =item C<BadBarcode>
 228
 229 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 230
 231 =item C<IsPermanent>
 232
 233 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.
 234
 235 =item C<DestinationEqualsHolding>
 236
 237 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.
 238
 239 =item C<WasReturned>
 240
 241 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.
 242
 243 =item C<ResFound>
 244
 245 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>.
 246
 247 =item C<WasTransferred>
 248
 249 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1173
1174 maxissueqty - maximum number of loans that a
1175 patron of the given category can have at the given
1176 branch.  If the value is undef, no limit.
1177
1178 This will first check for a specific branch and
1179 category match from branch_borrower_circ_rules.

1181 If no rule is found, it will then check default_branch_circ_rules
1182 (same branch, default category).  If no rule is found,
1183 it will then check default_borrower_circ_rules (default
1184 branch, same category), then failing that, default_circ_rules
1185 (default branch, default category).
1186
1187 If no rule has been found in the database, it will default to
1188 the buillt in rule:
1189
1190 maxissueqty - undef
1191
1192 C<$branchcode> and C<$categorycode> should contain the

1520 Unconditionally marks an issue as being returned by
1521 moving the C<issues> row to C<old_issues> and
1522 setting C<returndate> to the current date, or
1523 the last non-holiday date of the branccode specified in
1524 C<dropbox> .  Assumes you've already checked that
1525 it's safe to do this, i.e. last non-holiday > issuedate.

1527 Ideally, this function would be internal to C<C4::Circulation>,
