CLASS

WBA_Daemon - C++ well-behaved daemon

SYNOPSIS

WBA_Daemon class provides standard semantics for well-behaved daemons. This is an abstract base class and must be extended prior to use. Derived classes should provide their own version of Process().

MEMBER FUNCTIONS

virtual int Main(void)

Daemonize()

Initialize()

Process()

Finalize()

WBA_Application::exitCode

Process()

continueProcessing

virtual void Daemonize(void)
Perform the system-specific daemonization. For Unices, this function does a double fork, becomes the session leader, sets its working directory to the root directory, and clears its umask. For non-Unices, it does nothing. Derived classes wishing to daemonize only on certain conditions should over-ride Daemonize() with their own version.

virtual void Process(void)
Perform the main functionality of the daemon. Note that this function will be called infinitely until continueProcessing is set to false. This function is also responsible for setting WBA_Application::exitCode.

long GetContinueProcessing()
Get the current value of continueProcessing.

void SetContinueProcessing(const GPL_Boolean s)
Set the value of continueProcessing to s.
