vala Async and Yield Declare an Asynchronous Function
Example
public async int call_async () {
return 1;
}
call_async.begin ((obj, res) => {
var ret = call_async.end (res);
});
To call an asynchronous functions from a synchronous context, use the begin method and pass a callback to receive the result. The two arguments are:
objis aGLib.Objectif this call was defined in a classresis aGLib.AsyncResultholding the result of the asynchronous operation
The end method extract the result of the operation.
