#include "ltdic.h"

L_INT LDicomNet::SendAbort(nSource, nReason)

L_UCHAR nSource;	/* source of the abort */
L_UCHAR nReason;	/* reason for the abort */

Sends an Abort message to a connection. This function is available in the PACS Imaging Toolkit.

Parameter	Description
nSource	The source of the abort. Possible values are:
	Value	Meaning
	PDU_ABORT_SOURCE_USER	[0] Service user. (SCU)
	PDU_ABORT_SOURCE_PROVIDER	[2] Service provider. (SCP)
nReason	The reason for the abort. If the source of the abort is PDU_ABORT_SOURCE_USER, the reasons for the abort are not significant. If the source of the abort is PDU_ABORT_SOURCE_PROVIDER, the possible values are:
	Value	Meaning
	PDU_ABORT_REASON_UNKNOWN	[0] Unknown
	PDU_ABORT_REASON_UNRECOGNIZED	[1] Unrecognized PDU
	PDU_ABORT_REASON_UNEXPECTED	[2] Unexpected PDU
	PDU_ABORT_REASON_UNRECOGNIZED_PARAM	[4] Unrecognized PDU parameter
	PDU_ABORT_REASON_UNEXPECTED_PARAM	[5] Unexpected PDU parameter
	PDU_ABORT_REASON_INVALID_PARAM	[6] Invalid PDU parameter value

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

Calling LDicomNet::SendAbort generates a call to LDicomNet::OnReceiveAbort. At this time the DICOM Association is closed.

Please note that it is preferable to close a DICOM Association using the LDicomNet::SendReleaseRequest and LDicomNet::SendReleaseResponse. For more information on closing a DICOM Association, refer to Closing a DICOM Associate Connection.

Example

#define STATUS_SERVER 0x0001
L_INT LDicomNet__SendAbortExample(LMyDicomNet *m_pDicomNet,L_INT m_nStatus)
{
   //In this example, the m_pDicomNet object sends an abort message to the peer.
   //The m_pDicomNet can point to an object that is a server or a client
   //
   //LMyDicomNet is a class derived from LDicomNet
   //m_pDicomNet is a member variable declared as:
   //    LMyDicomNet *m_pDicomNet;
   //m_nStatus is member variable that identifies whether LDicomNet object is a server or client
   //m_nStatus can be (STATUS_NONE, STATUS_SERVER, STATUS_CLIENT)
   //    int m_nStatus;
   //
   //
   //In this example, assume
   //1. m_pDicomNet points to a valid object
   //2. A connection exists between client and server
   //3. An associate request has been sent and accepted
   //4. m_nStatus is either STATUS_SERVER or STATUS_CLIENT
   L_UINT32 lClients;
   LDicomNet *pDicomNet;
   L_INT nRet;
   
   if (m_nStatus == STATUS_SERVER)
   {
      //get the latest client
      lClients = m_pDicomNet->GetClientCount();
      pDicomNet = m_pDicomNet->GetClient(lClients - 1);
   }
   else //STATUS_CLIENT
   {
      pDicomNet = m_pDicomNet;
   }
  //send Abort message
  nRet =pDicomNet->SendAbort(PDU_ABORT_SOURCE_USER, 0);
  if(nRet > 0)
     return nRet;
