Determine if a name corresponds to a framebuffer object.

C Specification[edit]

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 .
