115 >Event handling allows your application to receive input from the user. Event handling is initalised (along with video) with a call to:
116 <PRE
117 CLASS="PROGRAMLISTING"
118 >SDL_Init(SDL_INIT_VIDEO);</PRE
119 >
120 Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like <A
121 HREF="sdlpollevent.html"
122 ><TT
123 CLASS="FUNCTION"
124 >SDL_PollEvent</TT
125 ></A
126 > and <A
127 HREF="sdlpeepevents.html"
128 ><TT
129 CLASS="FUNCTION"
130 >SDL_PeepEvents</TT
131 ></A
132 > you can observe and handle waiting input events.</P
133 ><P
134 >The key to event handling in SDL is the <A
135 HREF="sdlevent.html"
136 ><SPAN
137 CLASS="STRUCTNAME"
138 >SDL_Event</SPAN
139 ></A
140 > union. The event queue itself is composed of a series of <SPAN
141 CLASS="STRUCTNAME"
142 >SDL_Event</SPAN
143 > unions, one for each waiting event. <SPAN
144 CLASS="STRUCTNAME"
145 >SDL_Event</SPAN
146 > unions are read from the queue with the <TT
147 CLASS="FUNCTION"
148 >SDL_PollEvent</TT
149 > function and it is then up to the application to process the information stored with them.</P
