Write Data
After you send data over the transport connection with
write(), tirdwr passes data through the transport
provider. If you send a zero-length data packet, tirdwr discards the
message. If the transport connection is aborted, a hang-up condition is generated on the
stream and the write()
calls fail, and errno is set
to ENXIO. This problem might occur when the remote user aborts the
connection using t_snddis(). You can still retrieve any available data
after a hang-up. For more information, see the
write(2) an
t_snddis(3C) man pages.
