Member Function Documentation

◆ hasFeature()

bool OSystem_POSIX::hasFeature ( Feature f )

overridevirtual

Determine whether the backend supports the specified feature.

Reimplemented from ModularGraphicsBackend.

◆ displayLogFile()

bool OSystem_POSIX::displayLogFile ( )

overridevirtual

Open the log file in a way that allows the user to review it, and possibly email it (or parts of it) to the ScummVM team, for example as part of a bug report.

On a desktop operating system, this would typically launch some kind of an (external) text editor / viewer. On a phone, it can also cause a context switch to another application. Finally, on some ports, it might not be supported at all, and do nothing.

The kFeatureDisplayLogFile feature flag can be used to test whether this call has been implemented by the active backend.

Returns: True on success, false if an error occurred.

Note: An error might mean that the log file did not exist, or that the editor could not launch. However, a return value of true does not guarantee that the user will actually see the log file.; It is up to the backend to ensure that the system is in a state that allows the user to actually see the displayed log files. This might for example require leaving fullscreen mode.

Reimplemented from OSystem.

◆ init()

void OSystem_POSIX::init ( )

overridevirtual

Call this method once, after g_system is created.

Reimplemented from OSystem.

◆ initBackend()

void OSystem_POSIX::initBackend ( )

overridevirtual

The following method is called once, from main.cpp, after all config data (including command line params etc.) is fully loaded.

Note: Subclasses should always invoke the implementation of their parent class. They should do so near the end of their own implementation.

Reimplemented from BaseBackend.

◆ addSysArchivesToSearchSet()

void OSystem_POSIX::addSysArchivesToSearchSet	(	Common::SearchSet &	s,
		int	priority = `0`
	)

overridevirtual

Add system-specific Common::Archive objects to the given SearchSet. For example, on Unix, the directory corresponding to DATA_PATH (if set), or, on macOS, the 'Resource' dir in the app bundle.

Parameters

s	SearchSet to which the system-specific dirs, if any, are added.
priority	Priority with which those dirs are added.

Reimplemented from OSystem.

◆ getDefaultConfigFileName()

Common::Path OSystem_POSIX::getDefaultConfigFileName ( )

overrideprotectedvirtual

Get the default file name (or even path) where the user configuration of ScummVM will be saved.

Note that not all ports can use this.

Reimplemented from OSystem.

◆ getDefaultLogFileName()

Common::Path OSystem_POSIX::getDefaultLogFileName ( )

overrideprotectedvirtual

Get the default file name (or even path) where the scummvm.log will be saved.

Note that not all ports can use this.

Reimplemented from OSystem.

◆ createAudioCDManager()

AudioCDManager* OSystem_POSIX::createAudioCDManager ( )

overrideprotectedvirtual

Create the audio CD manager

Reimplemented from OSystem_SDL.
