What is the effect of a waiver of the right to appeal in a criminal case?

Defendant appealed and, upon his request, this court appointed counsel to represent him. Counsel has filed a brief under the authority of People v. Wende (1979) 25 Cal.3d 436 and Anders v. California (1967) 386 U.S. 738, setting forth a statement of the case and a few potential arguable issues: (1) whether the waiver of the right to appeal, as part of defendant's plea agreement, was valid; (2) whether defendant's guilty plea was constitutionally valid; and (3) whether his counsel was ineffective. Counsel has also requested this court to undertake a review of the entire record.
