install_keyboard - Installs the Allegro keyboard interrupt handler. SYNOPSIS
#include <allegro.h> int install_keyboard(); DESCRIPTION
Installs the Allegro keyboard interrupt handler. You must call this before using any of the keyboard input routines. Once you have set up the Allegro handler, you can no longer use operating system calls or C library functions to access the keyboard. Note that on some platforms the keyboard won't work unless you have set a graphics mode, even if this function returns a success value before calling set_gfx_mode. This can happen in environments with graphic windowed modes, since Allegro usually reads the keyboard through the graphical window (which appears after the set_gfx_mode call). Example: allegro_init(); install_timer(); install_keyboard(); /* We are not 100% sure we can read the keyboard yet! */ if (set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0) != 0) abort_on_error("Couldn't set graphic mode!"); /* Now we are guaranteed to be able to read the keyboard. */ readkey(); RETURN VALUE
Returns zero on success, or a negative number on failure (but you may decide not to check the return value as this function is very unlikely to fail). SEE ALSO

exzbuf - Z-buffered polygons demo. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exzbuf DESCRIPTION
This program demonstrates how to use Z-buffered polygons and floating point 3D math routines. It also provides a simple way to compute fps (frames per second) using a timer. After selecting a screen resolution through the standard GUI dialog, the example shows two 3D cubes rotating and intersecting each other. Rather than having full polygons incorrectly overlap other polygons due to per-polygon sorting, each pixel is drawn at the correct depth. SEE ALSO
