示例1: StackInit
func StackInit(u models.Usercorn, args, env []string) error {
exe := u.Exe()
addr, err := u.PushBytes([]byte(exe + "\x00"))
if err != nil {
return err
}
var tmp [8]byte
auxv, err := u.PackAddr(tmp[:], addr)
if err != nil {
return err
}
err = posix.StackInit(u, args, env, auxv)
if err != nil {
return err
}
// offset to mach_header at exe[0:] in guest memory
textOffset, _, _ := u.Loader().Header()
