Please see this simple code:

static void Task(void *lpArgument)

rt_printf("Task created.\n");
gNewTask = *(rt_task_self());
This fills the internal data structure RT_TASK with the content

Hi Jan,
thanks for your answer.
Yes, I tried it and even does not work. Changing code in this way:
#include
#include
#include
#include
RT_TASK* gNewTask;
static void Task(void *lpArgument)
{
rt_printf("Task created.\n");
gNewTask = rt_task_self();
}
int main()
{
RT_TASK tNewTask;
int err = rt_task_create(, "TEST", 16384, 10,
T_JOINABLE);
rt_printf(" task create: %d\n", err);
err = rt_task_start(, Task, NULL);
rt_printf(" task start: %d\n", err);
rt_task_sleep(20);
//err = rt_task_join();
err = rt_task_join(gNewTask);
rt_printf(" task join : %d\n", err);
return 0;
}
returns:
./test
task create: 0
Task created.
task start: 0
task join : -3
OK, then we have a regression. Let me check...

Thank you Jan for the patch.
BTW, I only tested the pointer case, but copying the content of RT_TASK
should actually work as well.
Thanks for reporting!

RT_TASK tNewTask;

T_JOINABLE);
rt_printf(" task create: %d\n", err);

//err = rt_task_join();
err = rt_task_join();
rt_printf(" task join : %d\n", err);
return 0;
}
Code is compiled using xeno-config --alchemy.
Using the rt_task_self() returned value with rt_task_join(), the latter
returns -ESRCH (no such process). Obviously if I use the local tNewTask
variable, return value is 0.
I'm pretty sure that this works without errors with Xenomai2.
Is it the expected behavior with Xenomai3?
Thanks in advance, regards
