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