The lists of flags at

and
<http://www.rpi.edu/dept/acm/packages/SDL/1.2.6/include/SDL/SDL_video.h>
has nothing remotely like -2147483648. I would expect something more
like 0x40000000
Am I using the wrong code to determine whether I have successfully set
DOUBLEBUF with
screen = pygame.display.set_mode((720,480), pygame.FULLSCREEN |
pygame.DOUBLEBUF)
AND
What does -2147483648 tell me? Does this number need converting?
From the interactive interpreter:-
>>> hex(-2147483648)
'-0x80000000'
>>> hex(pygame.FULLSCREEN)
'-0x80000000'
>>> hex(pygame.DOUBLEBUF)
'0x40000000'
