NAME

       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.
