//go:build tinygo

// Package sigtrap nudges TinyGo's cooperative scheduler to process pending
// signals.
//
// On Linux, TinyGo's os/signal handler records a signal but the scheduler only
// drains that record when it enters an idle wait. A relay almost always has a
// socket parked in netpoll, so the scheduler never reaches that path and
// SIGTERM would sit unprocessed until the next unrelated timer wakeup -- or
// never. Calling the runtime's checkSignals from a periodic goroutine closes
// that gap.
package sigtrap

import _ "unsafe"

//go:linkname checkSignals runtime.checkSignals
func checkSignals() bool

// Trap asks the runtime to hand any pending signal to os/signal.
func Trap() { checkSignals() }
