Detailed Description

This implements the basic skeleton of ExternalProgram and Process. Taking care of forking the process and setting up stdout and stderr so both implementations can use the same code

◆ pid()

pid_t zyppng::AbstractSpawnEngine::pid ( )

Returns: the pid of the forked process, without checking if the process is still running.

Definition at line 170 of file abstractspawnengine.cc.

◆ start()

virtual bool zyppng::AbstractSpawnEngine::start	(	const char const	argv,
		int	stdin_fd,
		int	stdout_fd,
		int	stderr_fd )

pure virtual

Kickstart the process, if this returns true it is guaranteed that exec() was successful

Implemented in zyppng::ForkSpawnEngine.

◆ waitForExit()

virtual bool zyppng::AbstractSpawnEngine::waitForExit ( const std::optional< uint64_t > & timeout = {} )

pure virtual

Implemented in zyppng::AbstractDirectSpawnEngine.

virtual bool zyppng::AbstractSpawnEngine::isRunning ( bool wait = false )

pure virtual

Implemented in zyppng::AbstractDirectSpawnEngine.

◆ notifyExited()

void zyppng::AbstractSpawnEngine::notifyExited ( int status )

virtual

Used to notify the backend that the process has ended, helpful when the process is tracked in another way than calling isRunning, for example in a eventloop.
