            object. If <parameter>id</parameter> is zero, or if <constant>id</constant> is not the name of a transform feedback object, or if an error
            occurs, <function>glIsTransformFeedback</function> returns <constant>GL_FALSE</constant>. If <parameter>id</parameter> is a name returned by
