GLISRENDERBUFFER(3G)						    OpenGL 3.3						      GLISRENDERBUFFER(3G)

NAME

       glIsRenderbuffer - determine if a name corresponds to a renderbuffer object

C SPECIFICATION

       GLboolean glIsRenderbuffer(GLuint renderbuffer);

PARAMETERS

       renderbuffer
	   Specifies a value that may be the name of a renderbuffer object.

DESCRIPTION

       glIsRenderbuffer returns GL_TRUE if renderbuffer is currently the name of a renderbuffer object. If renderbuffer is zero, or if
       renderbuffer is not the name of a renderbuffer object, or if an error occurs, glIsRenderbuffer returns GL_FALSE. If renderbuffer is a name
       returned by glGenRenderbuffers(), by that has not yet been bound through a call to glBindRenderbuffer() or glFramebufferRenderbuffer(),
       then the name is not a renderbuffer object and glIsRenderbuffer returns GL_FALSE.

NAME

       glDeleteRenderbuffers - delete renderbuffer objects

C SPECIFICATION

       void glDeleteRenderbuffers(GLsizei n, GLuint *renderbuffers);

PARAMETERS

       n
	   Specifies the number of renderbuffer objects to be deleted.

       renderbuffers
	   A pointer to an array containing n renderbuffer objects to be deleted.

DESCRIPTION

       glDeleteRenderbuffers deletes the n renderbuffer objects whose names are stored in the array addressed by renderbuffers. The name zero is
       reserved by the GL and is silently ignored, should it occur in renderbuffers, as are other unused names. Once a renderbuffer object is
       deleted, its name is again unused and it has no contents. If a renderbuffer that is currently bound to the target GL_RENDERBUFFER is
       deleted, it is as though glBindRenderbuffer() had been executed with a target of GL_RENDERBUFFER and a name of zero.

       If a renderbuffer object is attached to one or more attachment points in the currently bound framebuffer, then it as if
       glFramebufferRenderbuffer() had been called, with a renderbuffer of zero for each attachment point to which this image was attached in the
       currently bound framebuffer. In other words, this renderbuffer object is first detached from all attachment ponits in the currently bound
       framebuffer. Note that the renderbuffer image is specifically not detached from any non-bound framebuffers.

ERRORS

       GL_INVALID_VALUE is generated if n is negative.
