While sctp_send works well at me, sctp_sendmsg gives me an EINVAL as
soon as I pass in some flags. Nonetheless it still sends the message in
spite of returning the EINVAL. That looks like an error to me. Please
investigate the issue.
while( len > 0 && ( ( ret = sctp_sendmsg( sid, bufp, len, NULL, 0, 0,
MSG_NOSIGNAL, (0), 1000, 0 ) ) >= 0 || ( ret==-1 && ( errno == EINTR ||
errno == ENOBUFS ) ) ) ) { // returns EINVAL if flags are passed
if( ret >= 0 ) { bufp += ret; len -= ret; } else if( errno ==
ENOBUFS ) { struct timespec ts; ts.tv_sec=0; ts.tv_nsec=10000;
nanosleep(&ts,NULL); } }
if( ret == -1 ) perror ("error sending request to stream #(0)");
If you should be interested I can send the whole sctp test client
program.
