glIsFramebuffer determine if a name corresponds to a framebuffer object

## C Specification

GLboolean `glIsFramebuffer` GLuint framebuffer

## Parameters

framebuffer

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

## Description

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

A name returned by glGenFramebuffers, but not yet associated with a framebuffer object by calling glBindFramebuffer, is not the name of a framebuffer object.
