How to manually yield control to other Goroutines using runtime.Gosched()?

To manually yield control to other Goroutines using runtime.Gosched(), you can follow these steps:

Import the runtime package:

import "runtime"

Use the runtime.Gosched() function at the desired point in your Goroutine to yield control to other Goroutines. This function allows other Goroutines to be scheduled to run while the current Goroutine is suspended.

Here's an example of how you can use runtime.Gosched() in a Goroutine:

func main() {
    // Spawn Goroutine
    go myGoroutine()

    // Prevent main Goroutine from exiting immediately
    // You can replace this with other synchronization mechanisms like channels if needed.
    select {}
}

func myGoroutine() {
    for i := 0; i < 5; i++ {
        // Do some work

        // Yield control to other Goroutines manually using runtime.Gosched()
        runtime.Gosched()
    }
}

In this example, the myGoroutine() function is a Goroutine that performs some work inside a loop. By calling runtime.Gosched() within the loop, you explicitly yield control to other Goroutines, allowing them to execute. Once other Goroutines have run, the scheduler continues the execution of the current Goroutine from where it left off.

Keep in mind that explicit use of runtime.Gosched() is uncommon in most Go programs. The Go runtime's scheduler automatically handles scheduling Goroutines efficiently and fairly. Explicitly calling runtime.Gosched() should typically be avoided unless you have specific reasons to manually yield control.
