I am executing the following command:
(call-process "/usr/bin/echo" nil (:file "/tmp/test.txt") nil "hello")
According tothe documentaion this should redirect the output of th eproces to the file "/tmp/test.txt" but I have this error:
Symbol's function definition is void: :file
What am I doingwrong here? I use emcs 24.3.1 on GNU/Linux.

You need to quote the list, to prevent it from being evaluated as a
function call:
(call-process "/usr/bin/echo" nil '(:file "/tmp/test.txt") nil "hello")

Thanks! (and excuse me for the typos, I was typing too fast).
