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_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.
