Hello,

I'm finishing my driver with IRQ. I saw that there is two mode, Real 
time and Non real time for RTDM driver function.
My driver should run in the two mode. When I compile my User Space 
Shared library that call Xenomai Kernel driver,
I saw that library call every time Non real time function and no real 
time function...
I use a shared library with posix skin with makefile in attached file. I 
read explanation for static library with posix skin :

http://www.xenomai.org/index.php/Porting_POSIX_applications_to_Xenomai

What must I do with shared library for using rt mode ?
