Hi,

Can some one help for below queries

Is it possible to get goroutine id when we creted?

Is it possible to get goroutines count while we creating?

Is it possible to terminate a goroutine based on ID like if any goroutine has infinite loops?

Is it possible to clean up memory of variable like we have free in C?

Thanks,

Durga SomeswaraRao G.

The answer to all of the above questions, in the first approximation, is no.

Unsafe tricks may help to achieve some of those goals. What's the
purpose? Is this a XY problem?

If you want to identify goroutines at runtime, you can find in the attachments patches for Golang 1.10 to allow to assign a name to a goroutine.

These are patches against Golang 1.10 because I have been using the gccgo runtime that comes with GCC 8.4.

This could help you forward for what you want.
