DCMTK: DcmSCP, error:QueryRetrieveLevel larger remaining bytes

最近在DcmSCU发送一个findRequest后，DcmSCP总是报一个错误：

hi, all.

when i send a findRequest in DcmSCU, it will be successful to receive response.
but then the DcmServer will take place an error, as follows.

最后的解决方法是：

I have found the anwser Something about the findscu tool

we should implement the callback function to set response->DimseStatus=STATUS_Success;

Code:

typedef void (*DIMSE_FindProviderCallback)(
/* in */
void *callbackData,
OFBool cancelled, T_DIMSE_C_FindRQ *request,
DcmDataset *requestIdentifiers, int responseCount,
/* out */
T_DIMSE_C_FindRSP *response,
DcmDataset **responseIdentifiers,
DcmDataset **statusDetail);

DCMTK_DCMNET_EXPORT OFCondition
DIMSE_findProvider(
/* in */
T_ASC_Association *assoc,
T_ASC_PresentationContextID presIdCmd,
T_DIMSE_C_FindRQ *request,
DIMSE_FindProviderCallback callback, void *callbackData,
/* blocking info for data set */
T_DIMSE_BlockingMode blockMode, int timeout);

my callBack function:

Code:

void FindProviderCallback(
/* in */
void *callbackData,
OFBool cancelled, T_DIMSE_C_FindRQ *request,
DcmDataset *requestIdentifiers, int responseCount,
/* out */
T_DIMSE_C_FindRSP *response,
DcmDataset **responseIdentifiers,
DcmDataset **statusDetail)
{
if (responseCount>1)
{
//*responseIdentifiers=NULL;
response->DimseStatus=STATUS_Success;
}
else
{
if(request->DataSetType==DIMSE_DATASET_PRESENT) //or some other conditions are met
*responseIdentifiers=new DcmDataset(*requestIdentifiers);
}
}

Thanks all.
