func NotifyContext

func NotifyContext(parent context.Context, signals ...os.Signal) context.Context

NotifyContext returns a derived context from the parent context with a cancel function. It sets up a signal channel to listen for the specified signals and cancels the context when any of those signals are received. If a second signal is received, it exits the program with a status code of 1.

Example usage:

ctx := signal.NotifyContext(parentContext, os.Interrupt, syscall.SIGTERM)
go func() {
    <-ctx.Done()
    // Perform cleanup or other tasks before exiting
}()
