## 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 if renderbuffer is not the name of a renderbuffer object, or if an error occurs, `glIsRenderbuffer` returns `GL_FALSE`. If renderbuffer is a name returned by glGenRenderbuffers, by that has not yet been bound through a call to glBindRenderbuffer or glFramebufferRenderbuffer, then the name is not a renderbuffer object and `glIsRenderbuffer` returns `GL_FALSE`.
