glIsFramebuffer: determine if a name corresponds to a framebuffer object

Function Definition

 GLboolean glIsFramebuffer(GLuint framebuffer​);
Specifies a value that may be the name of a framebuffer object.


glIsFramebuffer returns GL_TRUE if framebuffer​ is currently the name of a framebuffer object. 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.
