  98 =head1 SYNOPSIS
  99
 100 use C4::Circulation;
 101
 102 =head1 DESCRIPTION
 103
 104 The functions in this module deal with circulation, issues, and
 105 returns, as well as general information about the library.
 106 Also deals with stocktaking.

 108 =head1 FUNCTIONS

 112 =head3 $str = &barcodedecode($barcode);
 113
 114 =over 4
 115
 116 =item Generic filter function for barcode string.
 117 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 118 Will do some manipulation of the barcode for systems that deliver a barcode
 119 to circulation.pl that differs from the barcode stored for the item.
 120 For proper functioning of this filter, calling the function on the
 121 correct barcode string (items.barcode) should return an unaltered barcode.

 198 =head2 transferbook
 199
 200 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
 201
 202 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 203
 204 C<$newbranch> is the code for the branch to which the item should be transferred.
 205
 206 C<$barcode> is the barcode of the item to be transferred.
 207
 208 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 209 Otherwise, if an item is reserved, the transfer fails.
 210
 211 Returns three values:
 212
 213 =head3 $dotransfer
 214
 215 is true if the transfer was successful.
 216
 217 =head3 $messages
 218
 219 is a reference-to-hash which may have any of the following keys:
 220
 221 =over 4
 222
 223 =item C<BadBarcode>
 224
 225 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 226
 227 =item C<IsPermanent>
 228
 229 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.
 230
 231 =item C<DestinationEqualsHolding>
 232
 233 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.
 234
 235 =item C<WasReturned>
 236
 237 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.
 238
 239 =item C<ResFound>
 240
 241 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>.
 242
 243 =item C<WasTransferred>
 244
 245 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1151 Retrieves circulation rule attributes that apply to the given
1152 branch and patron category, regardless of item type.
1153 The return value is a hashref containing the following key:
1154
1155 maxissueqty - maximum number of loans that a
1156 patron of the given category can have at the given
1157 branch.  If the value is undef, no limit.
1158
1159 This will first check for a specific branch and
1160 category match from branch_borrower_circ_rules.
1161
1162 If no rule is found, it will then check default_branch_circ_rules
1163 (same branch, default category).  If no rule is found,
1164 it will then check default_borrower_circ_rules (default
1165 branch, same category), then failing that, default_circ_rules
1166 (default branch, default category).
1167
1168 If no rule has been found in the database, it will default to
1169 the buillt in rule:
1170
1171 maxissueqty - undef
1172
1173 C<$branchcode> and C<$categorycode> should contain the
1174 literal branch code and patron category code, respectively - no
1175 wildcards.
