ldap_explode_rdn()--Break a Relative Distinguished Name into Its Components

 #include <ldap.h>
 
 char **ldap_explode_rdn(
                const char  *rdn,
                int          notypes)

The ldap_explode_rdn() function uses the relative distinguished name (RDN) in the local CCSID (as returned by ldap_explode_dn(), for example) and breaks it up into its component parts. If the RDN is in UTF8, use ldap_explode_rdn_utf8().

ldap_explode_rdn() returns a NULL-terminated array of character strings. The notypes parameter is used to request that only the component values be returned, not their types.

For example, the RDN "ou=Research+cn=Bob" would return as either {"ou=Research", "cn=Bob", NULL} or {"Research","Bob", NULL}, depending on whether notypes was 0 or 1, respectively. The result can be freed by calling ldap_value_free().

Authorities and Locks

No i5/OS authority is required.

Parameters

rdn

(Input) Specifies the RDN to be exploded (perhaps as returned by ldap_explode_dn()). Multiple RDNs can be concatenated using a plus sign ('+').

notypes

(Input) Specifies if type information is to be returned with each RDN. If non-zero, the type information will be stripped. If zero, the type information is retained. For example, setting notypes to 1 would result in the RDN "cn=Fido" being returned as "Fido".

Return Value

Components of Relative Distinguished Name (RDN)

if the request was successful.

NULL

if the request was not successful.

Error Conditions

If ldap_explode_rdn() is not successful, then there was no memory available for either the array or its component parts.
