keyboard_init - Man Page

initialize the keyboard to raw mode


#include <vgakeyboard.h>

int keyboard_init(void);
int keyboard_init_return_fd(void);


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_keypressed(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.

It is very likely that both are at least to some extent are due to Harm Hanemaayer <>.

Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
