glIsTransformFeedback 3G
glIsTransformFeedback determine if a name corresponds to a transform feedback object

## C Specification

GLboolean `glIsTransformFeedback` GLuint id

## Parameters

id

  Specifies a value that may be the name of a transform feedback object.

## Description

`glIsTransformFeedback` returns `GL_TRUE` if id is currently the name of a transform feedback object. If id is zero, or if `id` is not the name of a transform feedback object, or if an error occurs, `glIsTransformFeedback` returns `GL_FALSE`. If id is a name returned by glGenTransformFeedbacks, but that has not yet been bound through a call to glBindTransformFeedback, then the name is not a transform feedback object and `glIsTransformFeedback` returns `GL_FALSE`.
