L_DicomPrintSCUCreatePullPrintRequest

Syntax

#include "ltdic.h"

L_LTDIC_API L_INT L_DicomPrintSCUCreatePullPrintRequest(hPrintSCU, InstancesInfo, uInstancesCount, pParameters)

Parameters

HDICOMPRINTSCU hPrintSCU

A handle to Dicom Print SCU.

const pSTOREDPRINTSTORAGEINSTANCEINFO InstancesInfo

Referenced Stored Print.

L_UINT32 uInstancesCount

Count of Stored Print Instances.

const pPULLPRINTREQUESTPARAMETERS pParameters

Pull Print Request parameters.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Only one Pull Print Request SOP Instance can be supported on the Association at any time.

The function will not return until it receives the response of the Print SCP, or an error occurs. The function L_DicomPrintSCUGetLastOperationStatus can be used to obtain the status code specified in the response of the Print SCP. When the return value of the function CreatePullPrintRequest is 0, then the Pull Print Request SOP Instance was created successfully, with either a Success or Warning status code in the response of the Print SCP.

Having the Instance created, the function L_DicomPrintSCUGetPullPrintRequestInstanceUID can then be used to obtain its SOP Instance UID. Also, the functions L_DicomPrintSCUPrintPullPrintRequestSession and L_DicomPrintSCUDeletePullPrintRequest can be used to print the session and to delete the Instance, respectively.

At least one Stored Print Storage SOP Instance must be specified to be referenced. The information about each such Instance is specified using a STOREDPRINTSTORAGEINSTANCEINFO structure. Except for the member pszPatientID, if any string member of the structure is set to NULL or if the member specifies an empty string, the function will return an error.

The parameter pParameters points to a PULLPRINTREQUESTPARAMETERS structure that specifies the parameters to be used when creating the Pull Print Request SOP Instance. In this structure, if a string member is NULL, then the corresponding Attribute will not be included in the request to the Print SCP. Similarly, if a numeric member (that specifies an Attribute) is negative, the corresponding Attribute will not be included in the request. If pParameters is set to NULL, then the request will be sent without specifying any parameters.
