Exception handling!!!

Hi all,

I am using  openldap library in Mac os ( Snow leopard). Some time, my code crashes inside the "liblber".
I am using ldap_start_tls_s(). I think ldap_start_tls_s() is corrupting the ldap handle.
How can I catch the exceptions from the library?

In some link I found out that It supports exception handling.

thanks and regards,
Pratima
