108 Looks up a patron and returns information about him or her. If
109 C<$borrowernumber> is true (nonzero), C<&getpatroninformation> looks
110 up the borrower by number; otherwise, it looks up the borrower by card
113 C<$env> is effectively ignored, but should be a reference-to-hash.
115 C<$borrower> is a reference-to-hash whose keys are the fields of the
116 borrowers table in the Koha database. In addition,
117 C<$borrower-E<gt>{flags}> is a hash giving more detailed information
118 about the patron. Its keys act as flags :
120 if $borrower->{flags}->{LOST} {
121 # Patron's card was reported lost
124 Each flag has a C<message> key, giving a human-readable explanation of
125 the flag. If the state of a flag means that the patron should not be
126 allowed to borrow any more books, then it will have a C<noissues> key
129 The possible flags are:
135 Shows the patron's credit or debt, if any.
143 (Gone, no address.) Set if the patron has left without giving a
152 Set if the patron's card has been reported as lost.
160 Set if the patron has been debarred.
168 Any additional notes about the patron.
176 Set if the patron has overdue items. This flag has several keys:
178 C<$flags-E<gt>{ODUES}{itemlist}> is a reference-to-array listing the
179 overdue items. Its elements are references-to-hash, each describing an
180 overdue item. The keys are selected fields from the issues, biblio,
181 biblioitems, and items tables of the Koha database.
183 C<$flags-E<gt>{ODUES}{itemlist}> is a string giving a text listing of
184 the overdue items, one per line.
192 Set if any items that the patron has reserved are available.
194 C<$flags-E<gt>{WAITING}{itemlist}> is a reference-to-array listing the
195 available items. Each element is a reference-to-hash whose keys are
196 fields from the reserves table of the Koha database.

373 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
375 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
377 C<$newbranch> is the code for the branch to which the item should be transferred.
379 C<$barcode> is the barcode of the item to be transferred.
381 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
382 Otherwise, if an item is reserved, the transfer fails.
384 Returns three values:
388 is true if the transfer was successful.
392 is a reference-to-hash which may have any of the following keys:
398 There is no item in the catalog with the given barcode. The value is C<$barcode>.
402 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.
404 C<DestinationEqualsHolding>
406 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.
410 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.
414 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>.
418 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.
429 # FIXME - This function tries to do too much, and its API is clumsy.
430 # If it didn't also return books, it could be used to change the home
431 # branch of a book while the book is on loan.

439 # or failure, and set $C4::Circulation::Circ2::errmsg in case of
440 # failure. Or this function could return undef if successful, and an
