Re: [Firebird-devel] IBlob::putSegment
Not needed for me. At the moment I'm fine with IBlob, because so far the performance of my code is good enough. -- Mgr. Jiří Činčura https://www.tabsoverspaces.com/ Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel

Seems yes, IXpbBuilder in FB3 supports not all kinds of parameter blocks. But you still may use traditional way to build BPB, as described in IB6 docs. If needed support of IXpbBuilder::BPB may be backported to 3.0.8. That's trivial. Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel

What I found in "Using_OO_API.html" is just "Last two parameters are required only if you want to use blob filters or use stream blob, that's out of scope here.". That parameters are BPB (like DPB, but blob PB) and it's length. The simplest way to create one is using IXpbBuilder: IXpbBuilder* pb = utl->getXpbBuilder(, IXpbBuilder::BPB, NULL, 0); pb->insertInt(, isc_bpb_type, isc_bpb_type_segmented); pb->getBufferLength() and pb->getBuffer() are that 2 parameters what you should pass when creating blob. PS. I've thought creating various types of blobs is discussed in old Borland IB docs. Sorry if that's wrong.
