glIsTransformFeedback.3G - Man Page
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.
