idle: učinit proces 0 nečinným

Originální popis anglicky: idle - make process 0 idle

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <unistd.h> int idle(void);

POPIS / INSTRUKCE

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 super-user permission, will receive EPERM.

NÁVRATOVÁ HODNOTA

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

CHYBY / ERRORY

EPERM

Always, for a user process.

ODPOVÍDAJÍCÍ

This function is Linux-specific, and should not be used in programs intended to be portable.

NOTES

Since 2.3.13 this system call does not exist anymore.
