About creating files... when a file is opened, it will (generally) be created if it does not exist.
The first line will display "hello" on the screen. The second line sends "hello" into a file call datafile. If datafile pre-existed, whatever data used to be in it is lost. And if datafile did not exist, well it does now.

Hi,
Should the user jobs specified in crontab be running in background?
Cron daemon is already running in background. So I am not sure
whether should the jobs (output and error messages are redirected to file)
ran by it be explicitly stated to be run in background (& at end of command)
if one... (1 Reply)
I'm considering the merits of slightly redefining the "domain" field in a NIS netgroup (the third field in the triple) to make it more useful, in a new Internet Draft that I am currently developing. Does anyone out there who uses NIS actually make use of the "domain" field? The places I've worked... (8 Replies)
There is a program that we (a company I'm working for) would like to run once per day, and the approach we're taking is to create a fake user to give a location to the data for this program, and to be the user running the program. For the sake of the discussion, let me call the fake user "bob".

Hi
I'm currently rewriting a project from install-required to a pure runtime form.
The former had required the project name and the definition of the command as name, as they all become functions now, this could be shorter.
As you might have figured, the project already exists in another... (3 Replies)

create_datafile_index
create_datafile_index(3alleg4) Allegro manual create_datafile_index(3alleg4)NAME
create_datafile_index - Creates an index for a datafile. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
DATAFILE_INDEX *create_datafile_index(const char *filename);
DESCRIPTION
Creates an index for a datafile, to speed up loading single objects out of it. This is mostly useful for big datafiles, which you don't
want to load as a whole. The index will store the offset of all objects inside the datafile, and then you can load it quickly with
"load_datafile_object_indexed" later. Use destroy_datafile_index to free the memory used by it again.
Note: If the datafile uses global compression, there is no performance gain from using an index, because seeking to the offset still
requires to uncompress the whole datafile up to that offset. Example:
DATAFILE_INDEX *index = create_datafile_index("huge.dat");
DATAFILE *object = load_datafile_object_indexed(index, 1234);
...
unload_datafile_object(object);
destroy_datafile_index(index);
RETURN VALUE
A pointer value which you can pass to load_datafile_object_indexed.
