NAME
       glGetRenderbufferParameteriv - retrieve information about a bound renderbuffer object


C SPECIFICATION
       void glGetRenderbufferParameteriv(GLenum target, GLenum pname, GLint *params);


PARAMETERS
       target
           Specifies the target of the query operation.  target must be GL_RENDERBUFFER.

       pname
           Specifies the parameter whose value to retrieve from the renderbuffer bound to target.

       params
           Specifies the address of an array to receive the value of the queried parameter.


DESCRIPTION
       glGetRenderbufferParameteriv retrieves information about a bound renderbuffer object.  target specifies
       the target of the query operation and must be GL_RENDERBUFFER.  pname specifies the parameter whose value
       to query and must be one of GL_RENDERBUFFER_WIDTH, GL_RENDERBUFFER_HEIGHT,
       GL_RENDERBUFFER_INTERNAL_FORMAT, GL_RENDERBUFFER_RED_SIZE, GL_RENDERBUFFER_GREEN_SIZE,
       GL_RENDERBUFFER_BLUE_SIZE, GL_RENDERBUFFER_ALPHA_SIZE, GL_RENDERBUFFER_DEPTH_SIZE,
       GL_RENDERBUFFER_DEPTH_SIZE, GL_RENDERBUFFER_STENCIL_SIZE, or GL_RENDERBUFFER_SAMPLES.

       Upon a successful return from glGetRenderbufferParameteriv, if pname is GL_RENDERBUFFER_WIDTH,
       GL_RENDERBUFFER_HEIGHT, GL_RENDERBUFFER_INTERNAL_FORMAT, or GL_RENDERBUFFER_SAMPLES, then params will
       contain the width in pixels, the height in pixels, the internal format, or the number of samples,
       respectively, of the image of the renderbuffer currently bound to target.

       If pname is GL_RENDERBUFFER_RED_SIZE, GL_RENDERBUFFER_GREEN_SIZE, GL_RENDERBUFFER_BLUE_SIZE,
       GL_RENDERBUFFER_ALPHA_SIZE, GL_RENDERBUFFER_DEPTH_SIZE, or GL_RENDERBUFFER_STENCIL_SIZE, then params will
       contain the actual resolutions (not the resolutions specified when the image array was defined) for the
       red, green, blue, alpha depth, or stencil components, respectively, of the image of the renderbuffer
       currently bound to target.


ERRORS
       GL_INVALID_ENUM is generated if pname is not one of the accepted tokens.
