[Firebird-devel] IBlob::getSegment() and the last segment

2020-04-29 Thread Dmitry Sibiryakov 

  Hello, All.

  What should be the behavior of getSegment() reading the last segment of the 
BLOB?

a) Return some data of non-zero length and return RESULT_OK, next call shall return zero 
length data and RESULT_NO_DATA;

b) Return some data of non-zero length and return RESULT_NO_DATA.

  In examples folder there are two examples of BLOB reading and one assume behavior a) 
while second expects b). Which is wrong?
