Detailed Description

template<class SVC_HANDLER>
class ACE_Process_Strategy< SVC_HANDLER >

Defines the interface for specifying a concurrency strategy for a SVC_HANDLER based on multiprocessing.

This class provides a strategy that manages the creation of processes to handle requests from clients concurrently using a process-per-connection model. It behaves as a "process factory", using ACE::fork() to fork threads "on-demand" to run the service specified by a user-supplied SVC_HANDLER in a separate process.

Constructor & Destructor Documentation

template<class SVC_HANDLER >

ACE_Process_Strategy< SVC_HANDLER >::ACE_Process_Strategy	(	size_t	n_processes = `1`,
		ACE_Event_Handler *	acceptor = `0`,
		ACE_Reactor *	reactor = `0`,
		int	avoid_zombies = `0`
	)		`[inline]`

Initialize the strategy. If avoid_zombies is non-0 then set a flag to ACE::fork() to avoid zombies.

Member Function Documentation

template<class SVC_HANDLER >

int ACE_Process_Strategy< SVC_HANDLER >::activate_svc_handler	(	SVC_HANDLER *	svc_handler,
		void *	arg = `0`
	)		`[virtual]`

Activate the svc_handler with an appropriate concurrency strategy. This method activates the SVC_HANDLER by first forking and then calling the open() method of the SVC_HANDLER in the child.

Reimplemented from ACE_Concurrency_Strategy< SVC_HANDLER >.

void ACE_Process_Strategy< SVC_HANDLER >::dump ( void ) const

Dump the state of an object.
