This subclause introduces the pragma Asynchronous which allows a remote subprogram call to return prior to completion of the execution of the corresponding remote subprogram body.
Syntax
pragma Asynchronous(local_name);
Legality Rules
The local_name of a pragma Asynchronous shall denote either:
Static Semantics
A pragma Asynchronous is a representation pragma. When applied to a type, it specifies the type-related asynchronous aspect of the type.
Dynamic Semantics
A remote call is asynchronous if it is a call to a procedure, or a call through a value of an access-to-procedure type, to which a pragma Asynchronous applies. In addition, if a pragma Asynchronous applies to a remote access-to-class-wide type, then a dispatching call on a procedure with a controlling operand designated by a value of the type is asynchronous if the formal parameters of the procedure are all of mode in.
Implementation Requirements
Asynchronous remote procedure calls shall be implemented such that the corresponding body executes at most once as a result of the call.
