 137 =head1 NAME
 138
 139 C4::Circulation - Koha circulation module
 140
 141 =head1 SYNOPSIS
 142
 143 use C4::Circulation;
 144
 145 =head1 DESCRIPTION
 146
 147 The functions in this module deal with circulation, issues, and
 148 returns, as well as general information about the library.
 149 Also deals with inventory.
 150
 151 =head1 FUNCTIONS
 152
 153 =head2 barcodedecode
 154
 155   $str = &barcodedecode($barcode, [$filter]);
 156
 157 Generic filter function for barcode string.
 158 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 159 Will do some manipulation of the barcode for systems that deliver a barcode
 160 to circulation.pl that differs from the barcode stored for the item.
 161 For proper functioning of this filter, calling the function on the
 162 correct barcode string (items.barcode) should return an unaltered barcode.
 163
 164 The optional $filter argument is to allow for testing or explicit
 165 behavior that ignores the System Pref.  Valid values are the same as the
 166 System Pref options.

 257
 258 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 259
 260 C<$newbranch> is the code for the branch to which the item should be transferred.
 261
 262 C<$barcode> is the barcode of the item to be transferred.
 263
 264 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 265 Otherwise, if an item is reserved, the transfer fails.
 266
 267 Returns three values:
 268
 269 =over
 270
 271 =item $dotransfer
 272
 273 is true if the transfer was successful.
 274
 275 =item $messages
 276
 277 is a reference-to-hash which may have any of the following keys:
 278
 279 =over
 280
 281 =item C<BadBarcode>
 282
 283 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 284
 285 =item C<DestinationEqualsHolding>
 286
 287 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.
 288
 289 =item C<WasReturned>
 290
 291 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.
 292
 293 =item C<ResFound>
 294
 295 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>.
 296
 297 =item C<WasTransferred>
 298
 299 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1261 =item C<$borrower> is a hash with borrower informations (from Koha::Patron->unblessed).

1264

1266 Calculated if empty.
1267

1269

1276   - check for RENEWAL (book issued & being issued to the same patron)

1280           * RESERVE PLACED ?
1281               - fill reserve if reserve to this patron

1283           * TRANSFERT PENDING ?
