NAME
idle - make process 0 idle
SYNOPSIS
#include <unistd.h> int idle(void);
DESCRIPTION
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.
RETURN VALUE
idle() never returns for process 0, and always returns -1 for a user process.
ERRORS
EPERM Always, for a user process.
VERSIONS
Since 2.3.13 this system call does not exist anymore.
