When checking the documentation I found that a lot of rtdm functions are
indicated as available in user space, but AFAIK these functions are
only available in kernel space or interrupt contect.
The documentation is generated using ksrc/skin/rtdm/drvlib.c. Below is a
patch file that corrects this.
(I did not check other documentation to see if there are more functions
defined for use in user space)
Kind regards,
Johan Borkhuis

The problem is not "User-space task", but rather the headline
"Environments". The latter term is obviously not that clear. It is meant
to express the "Execution context" of the service caller. Would that
term make it clearer?
Thanks for picking this up,
Jan
