package main
// void a(long *p) {}
import "C"
import (
"unsafe"
)
//go:noinline
func b() {
x := int64(0)
C.a((*C.long)(unsafe.Pointer(&x)))
// do something without x
}
func main() {
b()
}
x should be considered unreachable after C.a . If x is something allocated
on heap, do I need to use runtime.KeepAlive(x) to make sure x will not be
garbage collected?
