I have a simple little test program, attached below. When I hit CTL-C
to break the program, not all of the "finished" lines will print. If I
remove either the rt_task_shadow call or the sigwait at the end, it will
then print all of them. Adding a fflush(stdout) to the end does nothing
to help it.
I'm not sure if there's some interaction with the Xenomai domain I am
just missing which is causing the print statements to be dropped.
This is running on a PowerPC kernel 2.6.24 with Xenoami 2.4.9.

#include <signal.h>
#include <stdio.h>
#include <native/task.h>
static volatile int signaled = 0;
static void catch(int x)
{
signaled = 1;
}
static RT_TASK rt_main;
int main(int argc, char **argv)
{
int sig;
struct sigaction act;
sigset_t set;
rt_task_shadow(&rt_main, NULL, 99, 0);
act.sa_flags = 0;
act.sa_handler = catch;
sigemptyset(&act.sa_mask);
sigaction(SIGINT,&act,NULL);
printf("starting 1\n");
printf("starting 2\n");
printf("starting 3\n");
printf("starting 4\n");
printf("starting 5\n");
while(!signaled)
{
sleep(1);
printf(".");
fflush(stdout);
}
printf("\nfinished 1\n");
printf("finished 2\n");
printf("finished 3\n");
printf("finished 4\n");
printf("finished 5\n");
sigfillset(&set);
sigwait(&set,&sig);
return 0;
}
