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.
