68 | <function>glRenderbufferStorage</function> is equivalent to calling | |
69 | <citerefentry><refentrytitle>glRenderbufferStorageMultisample</refentrytitle></citerefentry> with the | |

72 | <para> | |
73 | The target of the operation, specified by <parameter>target</parameter> must be <constant>GL_RENDERBUFFER</constant>. | |
74 | <parameter>internalformat</parameter> specifies the internal format to be used for the renderbuffer object's storage and | |
75 | must be a color-renderable, depth-renderable, or stencil-renderable format. | |
76 | <parameter>width</parameter> and <parameter>height</parameter> are the dimensions, in pixels, of the renderbuffer. | |
77 | Both <parameter>width</parameter> and <parameter>height</parameter> must be less than or equal to the value of | |
78 | <constant>GL_MAX_RENDERBUFFER_SIZE</constant>. | |
79 | </para> | |

81 | Upon success, <function>glRenderbufferStorage</function> deletes any existing data store for the renderbuffer | |
82 | image and the contents of the data store after calling <function>glRenderbufferStorage</function> are undefined. | |
