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() rou-
       tine 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.
