keyboard_update(3) Svgalib User Manual keyboard_update(3) NAME
keyboard_update, keyboard_waitforupdate - process raw keyboard events SYNOPSIS
#include <vgakeyboard.h> int keyboard_update(void); void keyboard_waitforupdate(void); DESCRIPTION
These routines check the keyboard buffer for any raw keyboard events and do the necessary updates to the internal buffers of key- board_clearstate(3) and keyboard_keypressed(3). When there are no such events, keyboard_update() returns 0 immediately (non-zero else) whereas keyboard_waitforupdate() blocks and waits until an event occurs. vga_waitevent(3) allows to wait for keyboard and other events at the same time.

keyboard_init(3) Svgalib User Manual keyboard_init(3) NAME
keyboard_init, keyboard_init_return_fd - initialize the keyboard to raw mode SYNOPSIS
#include <vgakeyboard.h> int keyboard_init(void); int keyboard_init_return_fd(void); DESCRIPTION
These routines initialize the keyboard to raw mode. No ASCII codes are produced, instead svgalib keeps track of each single keypress or depress. The return_fd version returns the file descriptor of the console device to allow you to do further tricks with it (though it is unclear which). The other version just returns 0 if successful. Both return -1 on error. keyboard_close(3) returns to normal operation. When in raw keyboard mode you can no longer use vga_getch(3) or vga_getkey(3) but you must use keyboard_getstate(3) or keyboard_key- pressed(3). Depending on the setting of keyboard_translatekeys(3) even in raw mode a <Ctrl>-C will cause a SIGINT. In any case svgalib will check for <Alt>-F1 - <Alt>-F10 and perform console switches accordingly. SEE ALSO
