Hi Prakash,
Unfortunately I don't have then anymore (I was testing in these examples to
adapt to my code) but I can try to help you.
>From what I understood, the idea is that you have to put the functions
rt_dev_sendto() and rt_dev_recvfrom() inside RT tasks. Here is part of my
main():
void main(void) {
...
signal(SIGTERM, catch_signal);
signal(SIGINT, catch_signal);
signal(SIGHUP, catch_signal);
mlockall(MCL_CURRENT|MCL_FUTURE);
rt_task_create(&rt_server_task, "Server", 0, 10, 0);
rt_task_start(&rt_server_task, server_msg, NULL);
...
}
outside of the functions, you will need to add:
RT_TASK rt_server_task;
and the rt_server_task itself:
void server_msg(void *arg) {
...
while (1) {
rt_dev_recvfrom(...) ;
...
}
}
OBS: Don't forget to add the task_delete in the end:
rt_task_delete(&rt_server_task);
OBS2: Look at docs for rt_task_set_periodic() and rt_task_wait_period() as
well.
Good luck!
