The KeDelayExecutionThread subroutine uses the current thread for a specified interval in a waiting state, which can be notified or not.

Syntax

  NTSTATUS KeDelayExecutionThread (  standby KPROCESSOR_MODE,   logical table of warnings,  PLARGE_INTEGER interval); 

Parameters

[inch]Specifies the CPU mode in which the caller is found, which can be KernelMode or UserMode. Lower-level drivers must specify KernelMode.

[inch]Indicates TRUE whether the timeout can be activated or not. Subordinate conductors must indicate FALSE.

[inch]Specifies the absolute relative time or time in units of 100 nanoseconds at which the wait type should occur. A harmful value indicates a relative time. Absolute expiration prolongs system time changes; changes to the program time do not affect significant expiration times.

Return Value

KeDelayExecutionThread usually returnGets the following values ​​describing how the delay ended:

Return code	Description
STATUS_ERFOLG	The timeout has expired because the specified interval has expired.
STATUS_ALERTE	Timed out because the thread was notified.
STATUS_USER_APC	The user-mode APC may have been delivered before the specified interval expired.

A

Note that the NT_SUCCESS macro generally recognizes all human status values ​​as “success values”.

The sequence must be timed, and the current thread can be put into idle state. After a certain interval, the winning chain will be paused and ready to start.

Alert table defines when a thread can be alerted and its wait state is terminated. For more information see Also expect APC .

If WaitMode is a UserMode parameter, some kernel stack can be swapped while waiting. Therefore, the caller never should try to pass parameters on the heap when calling KeDelayExecutionThread with a UserMode argument.

It is especially important to check the return value of KeDelayExecutionThread if the WaitMode UserMode or Alertable is TRUE, because KeDelayExecutionThread may return prematurely with a STATUS_USER_APC or STATUS_ALERTED status.

All long-term waits that can be canceled by a participant must be user-mode waits, and Alertable is set to FALSE.

If possible, Alertable should be set to FALSE and WaitMode should be set to KernelMode to simplify the drivers on the market.

The expiration time of the new delay is expressed either in absolute free time at which the delay should expire, or in time relative to the current system time. Although the Interval value is usually positive, the expiration time is often an absolute time. If this value is definitely negative, the timeout is equal to the same time.

Timeouts are measured in terms of the system clock, and the knowledge that the operating system can detectWhen the incredible timer expires, it is limited to the granularity of the system clock. For more information, see Timer precision .

Hello,
I started learning fast programming

For example, I want my driver to take advantage of every 2000ms

while (true)Sleep (2000); // (2 seconds)Do something();

The question is:
how to do it in the driver c
that must be why

during (1)Sleep function (2000); // What Does not existDo something();

Okay, I have a good hardware device – I’m writing to help you create a registry to reset the device, so I’ll have to wait for me to delete a certain value before I can proceed with the next operation.

What’s the safest way to do this? It is possible that there was a hardware problem and the device did not reboot, so it is not recommended to just run a loop. Inserting the counter into the loop is lame, as the counter may not be an accurate measurement for the evening depending on the processor speed (it may take 10ms to reset). And I’m pretty sure calling sleep () in the kernel driver is bad ™.

So is there a safe way to waste time with a kernel-mode driver? If there is a clock available from the kernel process, I can use it, but my Google Fu is weak today and nothing suitable came up.
