L_DicomSendCStoreRequest

#include "ltdic.h"

L_LTDIC_API L_INT L_DicomSendCStoreRequest(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nPriority, pszMoveAE, nMoveMessageID, hDS)

Sends a C-STORE-REQ message to a peer member of a connection.

Parameters

HDICOMNET hNet

A DICOM Network handle to the peer member of the connection.

L_UCHAR nPresentationID

Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.

L_UINT16 nMessageID

Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.

L_TCHAR * pszClass

Class affected by the request. This will be an SOP Class or an SOP MetaClass.

L_TCHAR * pszInstance

The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.

L_UINT16 nPriority

The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect. Possible values are:

Value Meaning
COMMAND_PRIORITY_LOW [0x0002] Low priority message.
COMMAND_PRIORITY_MEDIUM [0x0000] Medium priority message.
COMMAND_PRIORITY_HIGH [0x0001] High priority message.

L_TCHAR * pszMoveAE

Character string that contains the name of the application entity that originally requested the move. For a simple storage request from a client to a server, this should be ". When the request is a sub-operation of a C-MOVE, this will contain the name of the AE that requested the move.

L_UINT16 nMoveMessageID

The ID of the original move request message. For a simple storage request from a client to a server, this should be 0. When the request is a sub-operation of a C-MOVE, this will contain the original message ID of the C-MOVE request.

HDICOMDS hDS

Pointer to the data set to be stored.

Returns

Value Meaning
DICOM_SUCCESS The function was successful.
>0 An error occurred. Refer to Return Codes.

Comments

When an SCU requests a Move (C-MOVE-REQ), the SCP may have to call this function to request one or more C-STORE-REQ sub-operations to complete the storage. The series of calls and information transfer in a C-MOVE-REQ is complicated. For more information, refer to Moving Composite Data.

Calling this function generates a call to RECEIVECSTOREREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendCStoreResponse which will generate a call to RECEIVECSTORERESPONSECALLBACK.

Required DLLs and Libraries

Platforms

Win32, x64, Linux.
