See if you can find a newsgroup
where somebody should know what SDL is.

Details of how SDL (whatever it is) are not on topic
in comp.lang.c. If your problem is in SDL, you should
find a newsgroup that does that.

One generic C problem that could cause you woe is if
SDL_GetVideoInf o returns NULL. Perhaps you could
add a check for that prior to dereferencing the pointer?

You first have to initialize the library with SDL_Init.

When using a third-party library, it usually
helps tremendously to Read The Directions
before using.

Opps what? Sorry for what? Did you stub your toe and are now sorry for
doing so? Did you spend a little more of your check than you should have
and are now sorry that you are broke? Please provide enough context of
the previous post for others to know what you are replying to. Not all
news servers store the previous messages in a thread, therefore not all
others are able to go back to the previous article.
