glIsRenderbuffer determine if a name corresponds to a renderbuffer object

## C Specification

GLboolean `glIsRenderbuffer` GLuint renderbuffer

## Parameters

renderbuffer

  Specifies a value that may be the name of a renderbuffer object.

## Description

`glIsRenderbuffer` returns `GL_TRUE` if renderbuffer is currently the name of a renderbuffer object. If renderbuffer is zero, or is a non-zero value that is not currently the name of a renderbuffer object, or if an error occurs, `glIsRenderbuffer` returns `GL_FALSE`.

A name returned by glGenRenderbuffers, but not yet associated with a renderbuffer object by calling glBindRenderbuffer, is not the name of a renderbuffer object.
