NAME

     ldap_get_values,  ldap_get_values_len,  ldap_count_values  -
     LDAP attribute value handling routines

LIBRARY

     OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS

     #include <ldap.h>

     char **ldap_get_values(ld, entry, attr)
     LDAP *ld;
     LDAPMessage *entry;
     char *attr

     struct berval **ldap_get_values_len(ld, entry, attr)
     LDAP *ld;
     LDAPMessage *entry;
     char *attr

     ldap_count_values(vals)
     char **vals;

     ldap_count_values_len(vals)
     struct berval **vals;

     ldap_value_free(vals)
     char **vals;

     ldap_value_free_len(vals)
     struct berval **vals;

DESCRIPTION

     These routines are used to retrieve and manipulate attribute
     values from an LDAP entry as returned by ldap_first_entry(3)
     or ldap_next_entry(3).  ldap_get_values()  takes  the  entry
     and  the attribute attr whose values are desired and returns
     a NULL-terminated array of the attribute's values.  attr may
     be     an     attribute     type     as     returned    from
     ldap_first_attribute(3) or ldap_next_attribute(3), or if the
     attribute type is known it can simply be given.

     The number of values in the array can be counted by  calling
     ldap_count_values().   The  array  of values returned can be
     freed by calling ldap_value_free().

     If the attribute values are binary in nature, and  thus  not
     suitable  to  be  returned  as  an  array  of  char *'s, the
     ldap_get_values_len() routine can be used instead.  It takes
     the  same  parameters  as  ldap_get_values(),  but returns a
     NULL-terminated array of pointers to berval structures, each

     containing the length of and a pointer to a value.

     The number of values in the array can be counted by  calling
     ldap_count_values_len().   The  array of values returned can
     be freed by calling ldap_value_free_len().

ERRORS

     If    an    error    occurs    in    ldap_get_values()    or
     ldap_get_values_len(),  NULL  is  returned  and the ld_errno
     field in the ld parameter is set to indicate the error.  See
     ldap_error(3) for a description of possible error codes.

NOTES

     These routines dynamically allocate memory which the  caller
     must free using the supplied routines.
