L_BOOL LDicomAssociate::IsAsyncOperations(L_VOID)

Determines whether Asynchronous Operations are supported.


Value Meaning
TRUE The DICOM Associate supports Asynchronous Operations.
FALSE The DICOM Associate does not support Asynchronous Operations.


If a DICOM Associate connection does not support Asynchronous Operations, then an Application Entity must wait for the response from one message before sending another. If Asynchronous Operations are supported, multiple messages may be sent without waiting for a response. The number of messages that may be sent is set using LDicomAssociate::SetAsyncOperations.

To determine the number of Asynchronous Operations that may be invoked without a response, call LDicomAssociate::GetInvokedOperations. To determine the number of operations that have been completed, call LDicomAssociate::GetPerformedOperations.
