General API#

The general API is the main entrypoint into the rest of the API. It is unavailable for scripting through rot, as rot abstracts all usage of the API away.

Name	Specification	Description
tarnishPid	`INT32` property (read)	The PID of the system service. This is useful if you need to ack `SIGUSR1` or `SIGUSR2` signals.
apiAvailable	signal - (out) api `OBJECT_PATH`	Signal sent when an API has been successfully requested by something.
apiUnavailable	signal - (out) api `OBJECT_PATH`	Signal sent when an API is no longer available. This can happen for one of the following reasons: 1. All applications that have requested the API have released it (or exited). 2. Tarnish is shutting down and releasing all the APIs manually
aboutToQuit	signal	Signal sent when tarnish is about to exit. This allows background applications to gracefully exit.
requestAPI	method - (in) name `STRING` - (out) `OBJECT_PATH`	Request access to an API. Refused requests will return an `OBJECT_PATH` of `/`. Successful requests will return the `OBJECT_PATH` to the D-Bus interface for the API.
releaseAPI	method - (in) name `STRING`	Release your request for access to an API. This allows Tarnish to unregister the API if nothing is using it.
APIs	method - (out) `ARRA Y{STRING OBJECT_PATH}`	Request the list of available APIs on the system.

Example Usage:#

#include <liboxide.h>
#include "dbusservice_interface.h"
#include "systemapi_interface.h"

using namespace codes::eeems::oxide1;

int main(int argc, char* argv[]){
    Q_UNUSED(argc);
    Q_UNUSED(argv);

    auto bus = QDBusConnection::systemBus();
    General api(OXIDE_SERVICE, OXIDE_SERVICE_PATH, bus);
    qDebug() << "Tarnish PID:" << api.tarnishPid();
    qDebug() << "Requesting system API...";
    QDBusObjectPath path = api.requestAPI("system");
    if(path.path() == "/"){
        qDebug() << "Unable to get system API";
        return EXIT_FAILURE;
    }
    qDebug() << "Got the system API!";

    qDebug() << "Releasing system API...";
    api.releaseAPI("system");
    return EXIT_SUCCESS;
}
