glIsFramebuffer — determine if a name corresponds to a framebuffer object
GLboolean glIsFramebuffer( | GLuint framebuffer); |
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.
