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 pro-
     duced, instead svgalib keeps track of each single keypress or depress.  The
     return_fd version returns the file descriptor of the console device to  al-
     low  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.
