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

C Specification

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.
