[Xenomai-core] Fwd: Re: rt_task_delete doesn't work

[Roberto Bielli <roberto.bielli@domain.hid>]

Here is the example and the command.

RT_TASK pippo;
RT_TASK pluto;

void test1()
{
     int err;

     err = rt_task_delete(&pippo );
     if( err != 0 )
         printf("error task delete\n");

}

int main (int argc, char *argv[])
{
     //    Porta di comunicazione
     //int s;

     mlockall(MCL_CURRENT|MCL_FUTURE);

     // gestione signal handler
     //struct sigaction sa;
     //sa.sa_sigaction = (void *)sigHandler;
     //sigemptyset (&sa.sa_mask);
     //sa.sa_flags = SA_SIGINFO;

     //sigaction(SIGTERM,&sa, NULL);
     //sigaction(SIGINT,&sa, NULL);
     //sigaction(SIGPIPE,&sa, NULL);
     //sigaction(SIGFPE,&sa, NULL);
     //sigaction(SIGSEGV,&sa, NULL);


     char * namePippo = "pippo";
     char * namePluto = "pluto";
     int err;
     err = rt_task_create(&pippo, namePippo, 0x2000, 20, T_FPU );
     if( err != 0 )
         printf("error task create %s\n", namePippo );
     err = rt_task_create(&pluto, namePluto, 0x2000, 20, T_FPU );
     if( err != 0 )
         printf("error task create %s\n", namePluto );

     err = rt_task_start(&pluto, (void *)test1, NULL );
     if( err != 0 )
         printf("error task start %s\n", namePluto );

}
