LDAP_GET_VALUES(3)                                                                        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  con-taining containing
       taining 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 pos-sible possible
       sible error codes.

NOTES
       These routines dynamically allocate memory which the caller must free using the supplied routines.
