помогите понять,почему не компилируется (хочу объявить task_t а никак ((()

[чудо]

программа:
#include <linux/sсhed.h>
int main () {
task_t p;
return 0;
}

пытаюсь скомпилировать:

Вот такие пироги((( что я не так делаю?

[BlackStar]

C чего вы взяли что структура tast_t определена в <linux/shed.h> ?

[чудо]

а где она определена? извени,можт опечатки,но sched.h
ну впринципе даже не так интересна task_t,как task_struct а она именно там определена

чудо
А что мешает написать task_struct p ?

А что мешает написать task_struct p ?

По-видимому пример из LinuxFormat и Ogre3D =)
