Member Function Documentation

◆ initBackend()

void OSystem_Atari::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.

◆ createMutex()

Common::MutexInternal* OSystem_Atari::createMutex ( )
overridevirtual

Create a new mutex.

Returns
The newly created mutex, or 0 if an error occurred.

Implements OSystem.

◆ getMillis()

uint32 OSystem_Atari::getMillis ( bool  skipRecord = false)
overridevirtual

Get the number of milliseconds since the program was started.

Parameters
skipRecordSkip recording of this value by the event recorder. This might be needed particularly when we are in an on-screen GUI loop where the player can pause the recording.

Implements OSystem.

◆ delayMillis()

void OSystem_Atari::delayMillis ( uint  msecs)
overridevirtual

Delay/sleep for the specified amount of milliseconds.

Implements OSystem.

◆ getTimeAndDate()

void OSystem_Atari::getTimeAndDate ( TimeDate &  td,
bool  skipRecord = false 
) const
overridevirtual

Get the current time and date, in the local timezone.

On many systems, this corresponds to the combination of time() and localtime().

Implements OSystem.

◆ getGlobalKeymaps()

Common::KeymapArray OSystem_Atari::getGlobalKeymaps ( )
overridevirtual

Return a platform-specific global keymap.

Returns
Keymap with actions appropriate for the platform.

The caller will use and delete the return object.

For more information, see keymapper.

Reimplemented from OSystem.

◆ getHardwareInputSet()

Common::HardwareInputSet* OSystem_Atari::getHardwareInputSet ( )
overridevirtual

Register hardware inputs with keymapper.

Returns
HardwareInputSet with all keys and recommended mappings.

For more information, see keymapper.

Reimplemented from OSystem.

◆ quit()

void OSystem_Atari::quit ( )
overridevirtual

Quit (exit) the application.

Implements OSystem.

◆ logMessage()

void OSystem_Atari::logMessage ( LogMessageType::Type  type,
const char *  message 
)
overridevirtual

Log the given message.

It is up to the backend where to log the different messages. The backend should aim at using a non-buffered output for it, so that no log data is lost in case of a crash.

The default implementation outputs them on stdout/stderr.

Parameters
typeType of the message.
messageThe message itself.

Implements OSystem.

◆ addSysArchivesToSearchSet()

void OSystem_Atari::addSysArchivesToSearchSet ( Common::SearchSet &  s,
int  priority 
)
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
sSearchSet to which the system-specific dirs, if any, are added.
priorityPriority with which those dirs are added.

Reimplemented from OSystem.

◆ getDefaultConfigFileName()

Common::Path OSystem_Atari::getDefaultConfigFileName ( )
overridevirtual

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.
