Update of bug #27709 (project lwip):
Planned Release: 1.3.2 => 1.4.0
_______________________________________________________
Follow-up Comment #3:
I think I can see why netconn_recv is different: all the other netconn
functions return an err_t, whereas netconn_recv returns a buffer, so has to
use conn->err to indicate error status.
I think we should modify netconn_recv to return an error like the others, and
have it take a buffer pointer as an argument to the function. This will
involve an API change, but I think is justifiable given the nature of this
bug. However, because there will be an API change I'll mark this as 1.4.0
