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.
