[7] A sleep command is also part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2. [8] In PowerShell, sleep is a predefined command alias for the Start-Sleep cmdlet which serves the same purpose. [9] Microsoft also provides a sleep resource kit tool for Windows which can be used in batch files or the command prompt to pause the execution and ...
The following example will set the machine to sleep after 10 minutes and sleep the display after five minutes, but only when powered by the battery. pmset -b sleep 10 displaysleep 5. The following command will assign slightly different power management settings for circumstances where the machine is powered by the charger.
A typical sleep system call takes a time value as a parameter, specifying the minimum amount of time that the process is to sleep before resuming execution. The parameter typically specifies seconds, although some operating systems provide finer resolution, such as milliseconds or microseconds.
[7] Most operating systems (including Solaris, Mac OS X and FreeBSD) use a hybrid approach called "adaptive mutex". The idea is to use a spinlock when trying to access a resource locked by a currently-running thread, but to sleep if the thread is not currently running. (The latter is always the case on single-processor systems.) [8]
An operating system may provide variations of the wait call that allow a process to wait for any of its child processes to exit, or to wait for a single specific child process (identified by its process ID) to exit. Some operating systems issue a signal to the parent process when a child process terminates, notifying the parent process and ...
When it comes to saving energy, I think I do pretty well. My wife and I both drive high-MPG vehicles, we keep our thermostat at a relatively chilly 62°F during the daytime hours in winter, and we ...
Windows 2000 is the first Windows to support hibernation at the operating system level (OS-controlled ACPI S4 sleep state) without special drivers from the hardware manufacturer. A hidden system file named " hiberfil.sys " in the root of the boot partition is used to store the contents of RAM when the computer hibernates.
In System Preferences, Safe Sleep [8] is referred to as sleep. Since Safe Sleep also allowed state to be restored in an event of a power outage, unlike other operating systems, hibernate was never offered as an option. In 2005, some Macs running Mac OS X v10.4 began to support Safe Sleep. The feature saves the contents of volatile memory to the ...
