4 We need to evolve the API surface of BIO which is relevant to BIO_dgram (and the
5 eventual BIO_dgram_mem) to support APIs which allow multiple datagrams to be
23 on OSes which do not support `sendmmsg` or `sendmsg`.
28 - We do not have to expose functionality which we cannot guarantee

35 - For OSes which do not support `sendmmsg`, we emulate it using repeated
36 calls to `sendmsg`. For OSes which do not support `sendmsg`, we emulate it
