Hello.
I am trying to a write simple program that can listen for interrupts
produced by the keyboard in user-space.
At first I tried to do this using the native API, however I figured out
that this functionality is turned off by default. So I decided to use
the rtdm API.
I wrote the code using the rtdm_irq_* related functions/variables and
included the <rtdm/rtdm.h> header file.
However, upon trying to compile I get a bunch of undefined reference
errors. I read through the rtdm.h file and found that there are no
definitions of rtdm_irq* related variables or function declarations.
All of these things are defined in <rtdm/rtdm_driver.h>, which you
cannot include in non-kernel code.
I guess it is pretty obvious that I cannot do this from user space...
but maybe I am missing something?
The rtdm API manual includes a "Environments:This service can be called
from:" section. And the function "rtdm_irq_request" lists "User-space
task (RT, non-RT)". Doesn't this mean that it can be called from a
user-space program?
Thanks for any info you can provide.
Running Ubuntu with Xenomai-2.5.5.2, linux kernel 2.6.32 .
