 125
 126 C4::Members - Perl Module containing convenience functions for member handling
 127
 128 =head1 SYNOPSIS
 129
 130 use C4::Members;
 131
 132 =head1 DESCRIPTION
 133
 134 This module contains routines for adding, modifying and deleting members/patrons/borrowers
 135
 136 =head1 FUNCTIONS
 137
 138 =head2 GetMemberDetails
 139
 140 ($borrower) = &GetMemberDetails($borrowernumber, $cardnumber);
 141
 142 Looks up a patron and returns information about him or her. If
 143 C<$borrowernumber> is true (nonzero), C<&GetMemberDetails> looks
 144 up the borrower by number; otherwise, it looks up the borrower by card
 145 number.
 146
 147 C<$borrower> is a reference-to-hash whose keys are the fields of the
 148 borrowers table in the Koha database. In addition,
 149 C<$borrower-E<gt>{flags}> is a hash giving more detailed information
 150 about the patron. Its keys act as flags :
 151
 152     if $borrower->{flags}->{LOST} {
 153         # Patron's card was reported lost
 154     }
 155
 156 If the state of a flag means that the patron should not be
 157 allowed to borrow any more books, then it will have a C<noissues> key
 158 with a true value.
 159
 160 See patronflags for more details.
 161
 162 C<$borrower-E<gt>{authflags}> is a hash giving more detailed information
 163 about the top-level permissions flags set for the borrower.  For example,
 164 if a user has the "editcatalogue" permission,
 165 C<$borrower-E<gt>{authflags}-E<gt>{editcatalogue}> will exist and have
 166 the value "1".
