This command sets the display mode for the current program.
void dbSetDisplayMode ( int iWidth, int iHeight, int iDepth )
This command changes the display mode of the application to the specified mode. Here is an example of the command which sets the display mode to 640x480 resolution in 32-bit color:
dbSetDisplayMode ( 640, 480, 32 );
Though the application will not crash if the mode is unsupported, it is best to check for availability of the mode with the dbCheckDisplayMode function.
if ( dbCheckDisplayMode ( 800, 600, 32 ) ) dbSetDisplayMode ( 800, 600, 32 );
Also, it is notable that this can be called anywhere in a program multiple times. For example:
dbSetDisplayMode ( 640, 480, 32 ); /*large amounts of code*/ dbSetDisplayMode ( 800, 600, 32 );
This is very useful for in-game display options.
