I just spawned a task and I want to redirect it’s STDIN to ttyp3. I have to
do this form outside the task(right next to the spawn function call).
Can somebody please tell me how to do this?
Thank You
LP
Search for qnx_spawn_options in the doc.

more specifically, you want to get an fd to the tty
(open it for RDWR)
and then set the iov members of the qnx_spawn_options structure to point
to this fd. set iov[0] to iov[2] to the fd
then set your flags to set yourself as a session leader:
qnx_spawn_options.flags |= _SPAWN_SETSID | _SPAWN_TCSETPGRP
then call spawn[vpe]
