glIsTransformFeedback: determine if a name corresponds to a transform feedback object

Function Definition

 GLboolean glIsTransformFeedback(GLuint id​);
Specifies a value that may be the name of a transform feedback object.


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.
