2010 Khronos Group glIsFramebuffer 3G 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. glGenFramebuffers, glBindFramebuffer, glDeleteFramebuffers Copyright 2010 Khronos Group.
