L_DicomIsAsyncOperations

#include "ltdic.h"

L_LTDIC_API L_BOOL L_DicomIsAsyncOperations(hPDU)

Determines whether Asynchronous Operations are supported.

Parameters

HDICOMPDU hPDU

A DICOM Associate handle.

Returns

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

Comments

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 L_DicomSetAsyncOperations.

To determine the number of Asynchronous Operations that may be invoked without a response, call L_DicomGetInvokedOperations. To determine the number of operations that have been completed, call L_DicomGetPerformedOperations.
