I was saying for two feature readers inside same thread will result in
error.
Also, i would like to understand why SDF provider is not thread safe.

The SDF provider is per connection threaded which means only one thread
can access a reader at a time. You can have many threads using their own
connections/readers at the same time.

Hi,
I have issue when when more than one feature reader is created against
same SDF connection
It looks like same buffer ( created by sqlite cursor ) is shared betwean
feature readers.
This will cause that data returned from feature reader with function
GetGeometry will be corrupted when another reader is used.
Is this a bug or I am not looking into it correctly ?
I would like to be able to use multi thread access to sqlite database.
If I am right, SDF provider is not "thread safe" ? if so, what are main
reasons for it ?
Thank you,
Haris
