game programming library.
#include <allegro.h>
int keypressed();
Returns TRUE if there are keypresses waiting in the input buffer. You can use
this to see if the next call to readkey() is going to block or to simply wait
for the user to press a key while you still update the screen possibly drawing
some animation. Example:
while (!keypressed()) {
/* Show cool animated logo. */
}
/* So he skipped our title screen. */
