Daemonisation with a feedback

Annotation

This short article describes how to use in your application a proposed set of functions which simplifies building daemons with a feedback from a child process to a parent one.

---

The code has been tested with gcc 3.4.2 on Linux. Most probably it will work without changes on other platforms.

First version of the daemonisation functions set. It uses SIGUSR1 and SIGUSR2 sinals' handlers, two bool variables and the sleep call for waiting. It is good only because it was extensively used in some projects.

• The set of functions, an example and doxygen documentation:
  DaemonFramework1-full.tar.bz2 (28297 bytes) or
  DaemonFramework1-full.tar.gz (29731 bytes)
  
• The set of functions and an example without doxygen documentation:
  DaemonFramework1.tar.bz2 (14308 bytes) or
  DaemonFramework1.tar.gz (15939 bytes)
  
• Doxygen documentation of the set of functions.



Second version of the daemonisation functions set. It does not use global variables. It uses the sigwait call for waiting. It is not perfect only because it was not tested thorough in real applications.
• The set of functions, an example and doxygen documentation:
  DaemonFramework2-full.tar.bz2 (28307 bytes) or
  DaemonFramework2-full.tar.gz (29792 bytes)
  
• The set of functions and an example without doxygen documentation:
  DaemonFramework2.tar.bz2 (14447 bytes) or
  DaemonFramework2.tar.gz (16014 bytes)
  
• Doxygen documentation of the set of functions.
