Hi Community,
I’m working with blob manager to implement our design. The block diagram
in
GRExtras looks similar to this:
BLOCK 1 → BLOCK 2 → BLOCK 3 → SINK
Where, Block 1 contains the manager as follows:
MsgBlobManager = pmt::pmt_mgr::make();
for (size_t i = 0; i < MSG_BLOBS_ALLOCATION; i++)
{
MsgBlobManager->set(pmt::pmt_make_blob(BLOB_MSG_INITIAL_SIZE));
}
However, when I made some changes in the blob that is passing around in
BLOCK 2 (only 1 field of the blob), in BLOCK 3 I received the old data
from
BLOCK 1. This happens exactly 3 times until BLOCK 3 received the correct
updated data.
I’m not sure if it is related due to previous blocks are keeping a
reference to the incoming message (as explained in
Home · guruofquality/grextras Wiki · GitHub).
What I do not know either is the following:
“Normally, a PMT is created and passed to a downstream consumer. When
all
downstream consumers delete their references to the PMT, the object is
deconstructed and freed back into nothingness”
- How the downstream consumer delete their reference to a PMT object?
- Is it automatically done or should I explicitly do this?
Thanks for your time and advice,
Regards,
Jose.
