glIsFramebuffer - OpenGL ES 3.1 Reference Pages

## Name

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 if `framebuffer` is not the name of a framebuffer object, or if an error occurs, `glIsFramebuffer` returns `GL_FALSE`. If `framebuffer` is a name returned by glGenFramebuffers, by that has not yet been bound through a call to glBindFramebuffer, then the name is not a framebuffer object and `glIsFramebuffer` returns `GL_FALSE`.
