3 SDL_keysym\- Keysym structure
4 .SH "STRUCTURE DEFINITION"
18 Hardware specific scancode
30 The \fBSDL_keysym\fR structure is used by reporting key presses and releases since it is a part of the \fI\fBSDL_KeyboardEvent\fR\fR\&.
32 The \fBscancode\fR field should generally be left alone, it is the hardware dependent scancode returned by the keyboard\&. The \fBsym\fR field is extremely useful\&. It is the SDL-defined value of the key (see \fISDL Key Syms\fR\&. This field is very useful when you are checking for certain key presses, like so:
37 while(SDL_PollEvent(&event)){
40 if(event\&.key\&.keysym\&.sym==SDLK_LEFT)
52 \fBmod\fR stores the current state of the keyboard modifiers as explained in \fI\fBSDL_GetModState\fP\fR\&. The \fBunicode\fR is only used when UNICODE translation is enabled with \fI\fBSDL_EnableUNICODE\fP\fR\&. If \fBunicode\fR is non-zero then this a the UNICODE character corresponding to the keypress\&. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character:
56 if ( (keysym\&.unicode & 0xFF80) == 0 ) {
57 ch = keysym\&.unicode & 0x7F;
60 printf("An International Character\&.
65 UNICODE translation does have a slight overhead so don\&'t enable it unless its needed\&.
