remove_keyboard(3alleg4) Allegro manual remove_keyboard(3alleg4)NAME
remove_keyboard - Removes the Allegro keyboard handler.
SYNOPSIS
#include <allegro.h>
void remove_keyboard();
DESCRIPTION
Removes the keyboard handler, returning control to the operating system. You don't normally need to bother calling this, because alle-
gro_exit() will do it for you. However, you might want to call this during runtime if you want to change the keyboard mapping on those
platforms were keyboard mappings are needed. You would first modify the configuration variable holding the keyboard mapping and then rein-
stall the keyboard handler. Example:
remove_keyboard();
/* Switch to Spanish keyboard mapping. */
set_config_string("system", "keyboard", "es");
install_keyboard();

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).
