linux kernel - How to use setscheduler (what Includes are needed)? -

i trying use setscheduler (in linux (2.4) kernel) change parameters, tried compile file , got error:undefined reference. includes needed use setscheduler ? in advance help!

you're in luck, #include right @ top of man page :)

name        sched_setscheduler, sched_getscheduler - set ,        scheduling policy/parameters  synopsis        #include <sched.h> 

note functions named leading sched_. bit important too. :)
