syslog best practices -- when to call closelog?

J Rice

I have a question:

When should syslog.closelog () be called? I have a daemon that spends
most of its time asleep and quiet, but writes messages to the mail log
when active. Should I open the log at the start and keep it open until
the program closes? This seems much simpler than issuing three
commands everytime I want to write to the log.

The program will essentially be running constantly. Is having the log
constantly "open" a problem? What happens if the program crashes or is
killed without a closelog()?

In your terms, it's entirely safe to leave open the handle to syslog.
The operating system takes responsibility for cleanup on shutdown of
your application.

Javascript Best Practices Document v1.0

by: Matt Kruse | last post by:

http://www.JavascriptToolbox.com/bestpractices/ I started writing this up as a guide for some people who were looking for general tips on how to do things the 'right way' with Javascript.

The above URL is version 1.0 (draft) that resulted. IMO, it is not a replacement for the FAQ,...

fork + syslog blocking

by: Gregory Starck | last post by:

Hello, I'm having what seems to be a deadlock in syslog with the code (wich comes from a project I'm working on, but I've reduced the test case to its minimum) I put at the end of this messsage. It must be compiled with -lpthread. (so the fork could be also a possible cause of what I'm mentionning). The "bug" does not occur every times. So you should maybe launch the prog a few times before the block occurs.

Getting and Setting and best practise

Hi guys, I have an object which represents an "item" in a CMS "component" where an "item" in the most basic form just a field, and a "component" is effectively a table. "item" objects can be created and then added to "component" objects to build up the component definition. My dilemma comes in deciding how to read/write data to the "item"

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
