Hi, I’m not sure this is the right place to ask this kind of question, but, having not found a better forum, I’m trying my luck. Apologies in advance if this is outside the scope of the mailing list. That being said, my question is: given a successful return of recvmsg() for a SOCK_SEQPACKET SCTP socket, is there no stateless way to determine if the read data, for which the MSG_EOR flag is set, is the trailing “fragment” of a larger record (either due to partial delivery or an insufficient buffer passed to a prior call to recvmsg() which returned with the MSG_EOR flag cleared), rather than a “full” message? >From what I can tell, MSG_TRUNC, which would’ve solved my issue, isn’t implemented for SCTP. Regarding this topic, I’ve only found old discussions, including some suggestions to add SOCK_RDM, which never materialised. Many thanks for your time! Luci
