# 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 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`.
