ldap_search_ext_s: maximum no of entries

Hi,

In case of ldap_search_ext_s:

We can pass,how many entries we want. In my case i can retrieve only 100 entries at a time due to the size limit of my buffer.

But the ldap search which i am using will return 1000 entries. Is there any way through which i can retrieve 1000 entries in chunks of 100.

first time i will fetch 100 entries then again next 100 entries then again next 100 entries..... ... ...

In this way i will retrieve all the entries. Please tell me the way of fetching entries from LDAP.
