Subject: [Xenomai-help] system() call allowed from within RT task ?
Date: Tue, 15 Apr 2008 14:26:28 +0200 [thread overview]
Message-ID: <1071035914@domain.hid> (raw)
Hello,
within my application I use system() calls from within a xenomai task.
Is this allowed ?
The reason I'm asking this, is the following:
In my application I have multiple xenomai tasks. One of them is time critical (Task_A).
An other (non time critical) xenomai task (Task_B) is used to pass data back
and forth between Task_A and normal linux tasks. Task_B uses the system()-call
to accomplish certain requests.
I have set the T_WARNSW for Task_A in order to get a SIGXCPU, whenever it switches
to secondary mode. As long as Task_B is not executing a sytem() call, everything is fine.
But when for example Task_B executes a system("cp -R dirA dirB") the application terminates
due to a SIGXCPU signal.
I'm using
- Linux Kernel 2.6.17 (I-PIPE 1.5-02)
- Xenomai 2.3.0
- Celeron 600MHz System
Regards
Jochen
