What is the test for the forfeiture rule in criminal law?

"Complaints about the manner in which the trial court exercises its sentencing discretion and articulates its supporting reasons cannot be raised for the first time on appeal." (People v. Scott (1994) 9 Cal.4th 331, 356.) The forfeiture rule applies as long as the defendant was afforded a meaningful opportunity to object. (Ibid.) "[A] meaningful opportunity to object means that the defendant [must] be given the opportunity to address the court on the matter of sentence and to object to any sentence or condition thereof imposed by the court. In short, it refers to procedural due process . . . ." (People v. Zuniga (1996) 46 Cal.App.4th 81, 84 (Zuniga).)
