       ldap_get_values,  ldap_get_values_len,  ldap_count_values  - LDAP attribute value handling

       OpenLDAP LDAP (libldap, -lldap)

       #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;

       int ldap_count_values(vals)
       char **vals;

       int ldap_count_values_len(vals)
       struct berval **vals;

       void ldap_value_free(vals)
       char **vals;

       void ldap_value_free_len(vals)
       struct berval **vals;

       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

       ldap(3), ldap_first_entry(3), ldap_first_attribute(3), ldap_error(3)
