DeclareCallBackMBS.AllowAsync as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	DynamicDeclares	MBS Util Plugin	20.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Function: Whether the callbacks are allowed to go asynchronously.
Notes:
For MacOS/iOS only.

Asynchronous callbacks have no chance to return a value as the call to the Xojo event happens later and the C function returns before the Xojo event is started.
Synchronous callbacks would let the callback wait for the Xojo main thread to react to the event and then return the result back.

AllowAsync is set to true automatically for callbacks with void as return automatically.
