Hi Vlad, thanks for answering.

The BPB is correct, but allow me to elaborate my problem:

The blob is created with type stream indeed, as per isc_blob_info(), but it still behaves as a segmented blob. What do I mean by that:

1) I can read and write it with isc_get/put_segment().
2) isc_blob_info() shows correct number of segments and max. segment size.
3) reading the blob with isc_get_segment() does reads it in the exact same segments as it was written.
4) on a type 1 blob, isc_seek_blob() doesn't wanna seek and always returns 1.
5) on a type 0 blob isc_seek_blob() doesn't report an error in the status vector, but returns a garbage number instead.

Now,

I notice Bopen and BLOB_put are just light wrappers on top of isc_open_blob2, isc_put_segment respectively, so there's really no separate stream blob API underneath, which validates points 1,2,3. Can someone infirm/confirm this?

My problem really is with number 4 -- can someone confirm that isc_seek_blob() is really working in v2.5b2 ? I can't seem to find any C test case for this function.

Cosmin.
