glRenderbufferStorage â establish data storage, format and dimensions of a renderbuffer object's image
void glRenderbufferStorage( | GLenum  | target, |
|  | GLenum  | internalformat, |
|  | GLsizei  | width, |
|  | GLsizei  | height); |
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. +
+ 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.
+
+ 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.
