Re: [Arsperl-users] Missing parameter in ars_GetListEntry/GetListEntryWithFields

[Misi M. <mi...@rr...>]

Hi,

Yes, but my goal here is to utilize this feature to reduce the possibility
of timeouts.

I might have 10 million records in a table, and want to retrieve them in
chunks of say 10 000 or 100 000. It is then important to know if I managed
to retrieve everything, or if a server setting prevented me from getting
everything, or if it was exactly 100 000 records that matched my search
criteria.

I still think that we should add the possibility to use this parameter
that exists in the core API.

The question is how to change the ars_GetListEntry calls input/output
interface.
