The answer is provided by the compiler itself:
jnml@r550:~/src/tmp> cat main.go
package main
import (
"fmt"
/*
struct Test{
int ID;
};
struct Test * test(){
struct Test test;
test.ID=333;
return &test;
};
*/
"C"
)
func main() {
b := C.test()
fmt.Println(b.ID)
}
jnml@r550:~/src/tmp> go run main.go
# command-line-arguments
./main.go: In function ‘test’:
./main.go:14:6: warning: function returns address of local variable
[-Wreturn-local-addr]
return &test;
