LDAP_GET_VALUES(3)	   Library Functions Manual	    LDAP_GET_VALUES(3)

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;

       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;

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	struc-
       tures, 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.
