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_val-
       ues(),  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 indi-
       cate 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.
