keyboard_clearstate - reset the state of all keys when in raw keyboard mode
SYNOPSIS
#include <vgakeyboard.h>
void keyboard_clearstate(void);
DESCRIPTION
When in raw keyboard mode, svgalib receives press and release events from the kernel and keeps track which keys are currently pressed.
Calling keyboard_clearstate() sets this information to all keys released. You can use this for cleanup at certain places in your program.
In addition svgalib resets the states of all keys when a VC switch occurs because it does not know the current state of keys when it
regains control of the console.

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.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

I used to use ls -l cut to detrmine file size, and google searches didn't come up with anything else but 'stat' which doesn't appear on HPUX.
I discovered the humble 'wc -c' which does this job very neatly, and thought I would share it. (7 Replies)

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
