Description Joe Bestor 2006-07-09 20:40:56 UTC 
I'm going through the book, Focus on SDL. The author used SDL version 1.2.3 and 1.2.4. The authors program FOSDL3_1.CPP with 1.2.4 returns the following information on my system:

hw_available? 1
wm_available? 1
blit_hw? 1
blit_hw_CC? 1
blit_hw_A? 0
blit_sw? 1
blit_sw_CC? 1
blit_sw_A? 0
blit_fill? 1
video memory(in K)? 59104
bits per pixel? 32

The authors program with 1.2.11 returns the following information on my system:
hw_available? 0
wm_available? 1
blit_hw? 0
blit_hw_CC? 0
blit_hw_A? 0
blit_sw? 0
blit_sw_CC? 0
blit_sw_A? 0
blit_fill? 0
video memory(in K)? 0
bits per pixel? 32

May be that is because 1.2.3 used DirectX by default and 1.2.11 uses WinDib?
Comment 2 Sam Lantinga 2006-09-23 21:31:39 UTC 
That's correct.  You can test with the DirectDraw video driver by setting the SDL_VIDEODRIVER environment variable to directx
