   The Linux Programmer's Reference is not a relevant specification.  NuttX follows OpenGroup.org:  https://pubs.opengroup.org/onlinepubs/009695399/functions/recv.html .  The requirement there is compatible, but not identical:
   
   [EAGAIN] or [EWOULDBLOCK]
       The socket's file descriptor is marked O_NONBLOCK and no data is waiting to be received; or MSG_OOB is set and no out-of-band data is available and either the socket's file descriptor is marked O_NONBLOCK or the socket does not support blocking to await out-of-band data.
