Fixed bug #216 The attached files allow building the SDL library and tests with the Open Watcom compiler for Windows: - static library or DLL - Debug or Release builds available - uses register calling convention of Open Watcom - wmake target to build the SDL test samples Following is a table that shows what works and what doesn't, yet: checkkeys + graywin + loopwave + testalpha + testbitmap + testdyngl + testerror + testfile + testgamma + testgl + testhread + testiconv - (all failed) testkeys + testlock + (after removing calls to raise() from signal handler) testoverlay + (needs 'set SDL_VIDEODRIVER=directx') testoverlay2 + (-"-) testpalette + testplatform + testsem + testsprite + testtimer + testver + testvidinfo + testwin - (fading doesn't seem right) testwm + torturethread + testcdrom + testjoystick not tested threadwin + TODO: - make stack calling convention work (has linking issues with dxguid.lib) - perform testjoystick (I don't have a joystick) - investigate fading in testwin - merge with OS/2 port - add DOS target

>Event handling allows your application to receive input from the user. Event handling is initalised (along with video) with a call to:
<PRE
CLASS="PROGRAMLISTING"
>SDL_Init(SDL_INIT_VIDEO);</PRE
>
Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like <A
HREF="sdlpollevent.html"
><TT
CLASS="FUNCTION"
>SDL_PollEvent</TT
></A
> and <A
HREF="sdlpeepevents.html"
><TT
CLASS="FUNCTION"
>SDL_PeepEvents</TT
></A
> you can observe and handle waiting input events.</P
><P
>The key to event handling in SDL is the <A
HREF="sdlevent.html"
><SPAN
CLASS="STRUCTNAME"
>SDL_Event</SPAN
></A
> union. The event queue itself is composed of a series of <SPAN
CLASS="STRUCTNAME"
>SDL_Event</SPAN
> unions, one for each waiting event. <SPAN
CLASS="STRUCTNAME"
>SDL_Event</SPAN
> unions are read from the queue with the <TT
CLASS="FUNCTION"
>SDL_PollEvent</TT
> function and it is then up to the application to process the information stored with them.</P
