That of course is a significant issue.
I don't see what could prevent this from working.
I didn't say anything wouldn't work.
The simple method would be to create a new buffer for the data to be
transferred to the main thread and copy the data already received in a
"static buffer" there.
If you want to avoid copying you could transfer the data in the receive
buffer (which later would be freed) and allocate a new receive buffer
for the next receive.
I don't understand the "OS" issue, that you speak of .
Copying data tends to introduce a significant performance hit, which is
why many OSes try to avoid it by passing pointers. The typical result of
passing pointers is to introduce the possibility of buffer overflows,
because the lower-level (and more privileged) code doesn't (or can't)
apply application-specific tests.
