Description

hNet

A DICOM Network handle. This is the handle created by calling L_DicomCreateNet.

A DICOM Association handle. This is the handle created by calling L_DicomCreateAssociate.

Returns

DICOM_SUCCESS

Comments

Calling L_DicomSendAssociateRequest on an SCU generates a call to RECEIVEASSOCIATEREQUESTCALLBACK on the SCP. Within the callback function the SCP may accept or reject the Association request by calling L_DicomSendAssociateAccept or L_DicomSendAssociateReject.

A DICOM Association must be established between an SCU and an SCP before any DICOM messages or data can be transmitted between them. For more information on creating a DICOM Association, refer to Creating a DICOM Associate Connection.

When the DICOM Association is no longer needed, it should be ended. For more information, refer to Closing a DICOM Association.
