GLRENDERBUFFERSTORAG(3G)					   OpenGL Manual					  GLRENDERBUFFERSTORAG(3G)

NAME

       glRenderbufferStorage - establish data storage, format and dimensions of a renderbuffer object's image

C SPECIFICATION

       void glRenderbufferStorage(GLenum target, GLenum internalformat, GLsizei width, GLsizei height);

PARAMETERS

       target
	   Specifies a binding to which the target of the allocation and must be GL_RENDERBUFFER.

       internalformat
	   Specifies the internal format to use for the renderbuffer object's image.

       width
	   Specifies the width of the renderbuffer, in pixels.

       height
	   Specifies the height of the renderbuffer, in pixels.

DESCRIPTION

       glRenderbufferStorage is equivalent to calling glRenderbufferStorageMultisample() with the samples set to zero.

       The target of the operation, specified by target must be GL_RENDERBUFFER.  internalformat specifies the internal format to be used for the
       renderbuffer object's storage and must be a color-renderable, depth-renderable, or stencil-renderable format.  width and height are the
       dimensions, in pixels, of the renderbuffer. Both width and height must be less than or equal to the value of GL_MAX_RENDERBUFFER_SIZE.

       Upon success, glRenderbufferStorage deletes any existing data store for the renderbuffer image and the contents of the data store after
       calling glRenderbufferStorage are undefined.

ERRORS

       GL_INVALID_ENUM is generated if target is not GL_RENDERBUFFER.

       GL_INVALID_VALUE is generated if either of width or height is negative, or greater than the value of GL_MAX_RENDERBUFFER_SIZE.

       GL_INVALID_ENUM is generated if internalformat is not a color-renderable, depth-renderable, or stencil-renderable format.

       GL_OUT_OF_MEMORY is generated if the GL is unable to create a data store of the requested size.

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.
