if I call glClearColor() with arguments greater than 1 or less than 0
say glClearColor( 1.1, -0.1, 2, 1)and then
query the set clearing color as
glGetFloatv (GL_COLOR_CLEAR_VALUE, INTO_SOME_ARRRAY)

then what do you think it will return.

It think it will return the set values.But it is not doing that!!why?????...

FYI : the prototype for glClearColor is
glClearColor(GLclampf red, GLclampf green,
GLclampf blue, GLclampf alpha) ;

Since the datatype is GLclapf, all values you pass will be cut to fit into the range[1, 0]. So I assume glGetFloatfv returns {1, 0, 1, 1}.
