Ldap Query

I have a need to query a LDAP server from RPG.  I've been looking at a
couple of examples that Scott Klement posted, but I'm having some
problems.  
I really don't know much about LDAP, so I'm kinda fumbling around.  
Reading documentation, if I understand correctly, I should be able to
query a non-iseries LDAP  
Also, the LDAP_INIT should return a *NULL if request was not successful.

So, I started putting erroneous values as a Host name like

c                   eval      ld = ldap_init('NOGOOD': LDAP_PORT)

However I still get a pointer back.  Why?
It seems I can put any value as the first parm and still not return a
*NULL.

Is there anyway to verify that what is returned is correct?

Thanks
