I need to access the X11 Display* pointer used by SDL in order to go around
the
SDL abstraction to communicate with a lower-level library.

The Display* is stored in current_video->hidden->X11_Display within SDL. I
cannot find a way to access current_video or get the Display* value
directly
from SDL.

Suggestions?

Morgan,

look in SDL_syswm.h there’s a system dependant struct that on unix
systems contains the Display pointer. To fill that struct do as follows:

SDL_SysWMinfo info;
SDL_VERSION( &info.version );
SDL_GetWMInfo( &info );

Hope that helps.

According to the documentation, “You can only call [SDL_PumpEvents()] in
the thread that set the video mode.” In fact, SDL_PumpEvents() seems to be
dependent on SDL_Init(), rather than SDL_SetVideoMode().

The following program (shortened as much as possible) displays a window for
five seconds:

#include “SDL.h”
#include “SDL_thread.h”
#undef main

int
event_loop( void *init )
{
Uint32 start;

SDL_Init( SDL_INIT_VIDEO );
SDL_CondSignal( (SDL_cond *)init );

start = SDL_GetTicks();
while( SDL_GetTicks() - start < 5000 ) {
SDL_PumpEvents();
SDL_Delay( 1 );
}

return 0;
}

int
main()
{
SDL_Thread *thread;
SDL_cond *initialized;
SDL_mutex *init_mutex;
SDL_Surface *screen;

initialized = SDL_CreateCond();
thread = SDL_CreateThread( event_loop, initialized );

init_mutex = SDL_CreateMutex();
SDL_mutexP( init_mutex );
SDL_CondWait( initialized, init_mutex );

screen = SDL_SetVideoMode( 800, 600, 32, SDL_SWSURFACE );

SDL_WaitThread( thread, NULL );
SDL_Quit();

return 0;
}

high,

this is only my second post on this mailing list, and so far i love
it. i cant find ANYONE on the internet who knows anything about SDL.
its really a shame because this API is so great. i wish this was a
forum =). anyway, i just finished making my first game (a pong clone
with a twist). and i would REALLY appreciate it if someone would check
out my code and critisize it and tell me if im doing anything
extremely wrong. i put this on gamedev forums, but people just played
the game and didnt look at the source because no one knows SDL. thats
why im turning to you guys. heres the link to get the game/source

http://dpunchprod.150m.com

or if that link is down go to

http://www.geocities.com/graveyardfilla44

as soon as you go to one of those pages you will be shown a link to
download the .exe or the .zip for the source. thanks guys, i
appreciate it!!

ps- if you do read it, forgive me when you get to the draw_score
function. i know its sloppy, but i got to lazy to fix it =)

Take off on a romantic weekend or a family adventure to these great
U.S. locations. http://special.msn.com/local/hotdestinations.armx

I probably should have mentioned this also when I was explaining
spudder’s post. I think you forgot to free the surface of your games and
freed the sound too. When I press escape in the game, the music stops
playing where it is and just keeps playing that last note continuously
like an annoying pitch. Know what I mean?

I want to use GUIlib the little GUI api used in some samples. Im trying
to
use it in windows
I compile the dll perfectly 0 errors 0 warnings. But I dont know how to
obtain
the .lib file from the project. Is there some setting in the properties
what I am
missing ?
I am using VC6 .

Thanks in advance.

Try setting the path of your output file by hand to ($OUTDIR)/mylib.lib
or something like that (sorry - don’t have vc here now). VC does
something like ($OUTDIR)/($PROJECTNAME).lib - that doesn’t work.

Your program will run just fine, but it won’t actually get any events.
SDL doesn’t crash if you call SDL_PumpEvents() in another thread, it
just won’t do anything.

See ya!

I changed the PumpEvents() call to PollEvent() and it handles an SDL_QUIT
event fine. Is there, in fact, any dependency on SetVideoMode(), or can I
safely leave the event loop in its own thread?
