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. glIsTransformFeedback glGenTransformFeedbacks, glBindTransformFeedback, glDeleteTransformFeedbacks Copyright 2010-2014 Khronos Group.
