2010 Khronos Group glIsTransformFeedback 3G glIsTransformFeedback determine if a name corresponds to a transform feedback object GLboolean glIsTransformFeedback GLuint id 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. glGenTransformFeedbacks, glBindTransformFeedback, glDeleteTransformFeedbacks Copyright 2010 Khronos Group.
