[Click] #include <unistd.h> header in kernel ?

[ndritsos]

Hello everyone ,

i have created an element that uses  the library unistd.h,  and in the 
user level it works fine .
Now i'm working in kernel level , and it doesn't work.

in kernel level i have imported :

#include <linux/unistd.h>

and i have this  compile time error:
