glIsRenderbuffer: determine if a name corresponds to a renderbuffer object
GLboolean glIsRenderbuffer(GLuint renderbuffer);
- Specifies a value that may be the name of a renderbuffer object.
glIsRenderbuffer returns GL_TRUE if renderbuffer is currently the name of a renderbuffer object. If renderbuffer is zero, or if renderbuffer is not the name of a renderbuffer object, or if an error occurs, glIsRenderbuffer returns GL_FALSE. If renderbuffer is a name returned by glGenRenderbuffers, by that has not yet been bound through a call to glBindRenderbuffer or glFramebufferRenderbuffer, then the name is not a renderbuffer object and glIsRenderbuffer returns GL_FALSE.
