ldap_get_values, ldap_get_values_len, ldap_count_values - LDAP attribute value handling routines

OpenLDAPSoftware is developed and maintained by The OpenLDAP Project <http://www.openldap.org/>. OpenLDAPSoftware is derived from the University of Michigan LDAP 3.3 Release. OpenLDAP 2.6.9+dfsg-2ubuntu1 2024/11/26 LDAP_GET_VALUES(3)

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().

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.

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