If framebuffer is zero, or if framebuffer is not the name of a framebuffer object, or if an error occurs, glIsFramebuffer returns GL_FALSE. If framebuffer is a name returned by glGenFramebuffers, by that has not yet been bound through a call to glBindFramebuffer, then the name is not a framebuffer object and glIsFramebuffer returns GL_FALSE. glGenFramebuffers, glBindFramebuffer, glDeleteFramebuffers Copyright 2010-2013 Khronos Group.
