Hello,
Is there a way to make a
rt_event_pulse.
A kernel function rtdm_event_pulse is available, but no user space
function.
rtdm_event_pulse() is part of the inter-driver API, which explains why
there is no userland access to it. Assuming you need to wake up a RTDM
task waiting on a particular event via rtdm_event_wait(), then you
have to implement an rt/nrt ioctl handler in your RTDM driver which
will send the event. Userland can issue this ioctl request from
userland.
Hi,
in userspace there are rt_event_signal & rt_event_clear, but no
rt_event_pulse.
i need rt_event_pulse to make my source compatible with EventPulse
Window-Function.
You mentioned both rt_event_pulse, and rtdm_event_pulse in your
initial post, which is confusing: those are two different APIs.
RT_EVENTs - posted by rt_event_signal - from the native API are not
what you look for. Check the RT_SEM object, with rt_sem_create() using
the S_PULSE flag.
Thanks,
i will looking for rt_sem_create and S_PULSE.
Regards
Johann
