Sleep Dev C++ Windows

Oct 17, 2017 You can also press the Windows logo key + X on your keyboard, and then select Shut down or sign out Hibernate. For Windows 8.1 / Windows RT 8.1, move your mouse to the lower left-hand corner of the screen and right-click the Start button or press Windows logo key + X on your keyboard.

The PwrTest Sleep Scenario facilitates automated testing of sleep and resume transitions.

PwrTest is capable of directing the platform into one or more sleep states in an automated fashion and logging sleep state performance information such as the BIOS initialization and total resume times.

  • Sleep function in Windows, using C. Ask Question Asked 9 years, 8 months ago. I was searching for some sleep function in windows C, except Sleep.
  • Mar 07, 2017  Our goal for MSVC is to be the best compiler choice on Windows for targeting Windows, regardless of what editor or IDE you choose to use. We aim to deliver on our goal with continuous investments in the following key areas: full C conformance, better errors and warnings, runtime performance, reliability, build throughput, and the best security.
  • The principle is exactly the same as creating delays in user mode. Sleep has very limited value and you can use Google to find out why. Ultimately you need waitable timers.

/c:n
Specifies the number of cycles (1 is the default) to run.

/d:n
Specifies the delay time in seconds (90 is the default).

/p:n
Specifies the sleep time in seconds (60 is default). If wake timer isn't supported for hibernate, the system will restart and immediately resume after writing the hibernation file) .

/h:{y|n}
Specifies whether hybrid sleep should be enabled (y) or disabled (n). The default is system policy.

/s:{1|3|4|all|rnd|hibernate|standby}

1
Specifies that the target state is always S1.

3
Specifies that the target state is always S3.

4
Specifies that the target state is always S4.

all
Specifies cycling through all supported power states in order.

rnd
Specifies cycling through all supported power states randomly.

hibernate
Specifies target state is always hibernate (S4).

standby
Specifies target state is any available Standby state (S1 or S3).

/unattend
Specifies not to change system execution state after wakeup.

/e:n
Specifies the timeout in seconds to wait for the transition end event (120 seconds is the default) .

Examples

XML log file output

The following table describes the XML elements that appear in the log file.

ElementDescription
<SleepScenario>

Contains information related to the sleep scenario. There is only one <SleepScenario> element in a PwrTest log file.

<SleepTransitions>

Provides overall data about the sleep transition cycles such as the state of critical and hybrid sleep features.

<SleepTransition>

Provides per-sleep cycle information such as the start and end times, as well as details about the resume time, such as the BIOS initialization time. A <SleepTransition> element is generated for each sleep transition cycle.

<StartT>

Indicates the start time of the sleep cycle. (hh:mm:ss)

<EndT>

Indicates the end time of the sleep cycle. (hh:mm:ss)

<Duration>

Indicates the duration of the sleep cycle. (hh:mm:ss)

<TargetState>

Indicates the target sleep state.

<EffectiveState>

Indicates the effective sleep state.

<BIOSInit>

Indicates the amount of time required to initialize the BIOS (TargetState must be 3) on resume in milliseconds.

<DriverInit>

Indicates the amount of time required to initialize drivers on resume in milliseconds.

<Suspend>

Indicates the amount of time required to suspend the system in milliseconds.

<Resume>

Indicates the total amount of time required to resume the system in milliseconds.

<HiberRead>

Indicates the time required to read the hibernation file in milliseconds. (TargetState must be 4)

<HiberWrite>

Indicates the time required to write the hibernation file in milliseconds. (EffectiveState must be 4)
