ОПИСАНИЕ

       idle() is an internal system call used during bootstrap.  It
       marks the process's pages as swappable, lowers its priority, and
       enters the main scheduling loop.  idle() never returns.

       Only process 0 may call idle().  Any user process, even a process
       with superuser permission, will receive EPERM.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       idle() never returns for process 0, and always returns -1 for a
       user process.

ОШИБКИ

       EPERM  Always, for a user process.
