How to prevent Goroutines from being preempted using runtime.LockOSThread()?

To prevent Goroutines from being preempted using runtime.LockOSThread(), you can follow these steps:

Import the "runtime" package in your code: import "runtime"
Use the runtime.LockOSThread() function before starting a Goroutine. This function ensures that the Goroutine will always run on the same OS thread and will not be preempted by other Goroutines.

Example:

go func() {
    runtime.LockOSThread()
    defer runtime.UnlockOSThread()

    // Your Goroutine logic

}()

Make sure to call runtime.UnlockOSThread() using the defer statement to ensure that the OS thread is released after the Goroutine finishes execution.

Note: While using runtime.LockOSThread() can prevent Goroutines from being preempted, it is important to use it judiciously. Locking OS threads can limit Goroutine scheduling and lead to performance issues. Therefore, it is recommended to use it only when necessary and based on specific requirements.
