LDicomNet::Connect

#include "ltdic.h"

L_INT LDicomNet::Connect(pszHostAddress, nHostPort, pszPeerAddress, nPeerPort)

L_TCHAR * pszHostAddress;	/* host IP address */
L_UINT nHostPort;	/* host port number */
L_TCHAR * pszPeerAddress;	/* peer IP address */
L_UINT nPeerPort;	/* peer port number */

Connects an SCU to an SCP. This function is available in the PACS Imaging Toolkit.

Parameter	Description
pszHostAddress	Character string that contains the IP address of the host computer (the SCU's address).
nHostPort	Port number of the host (the SCU's port).
pszPeerAddress	Character string that contains the IP address of the peer computer to which to connect (the SCP's address).
nPeerPort	Port number of the peer computer to which to connect (the SCP's port).

Returns

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

Comments

If pszHostAddress is "" or NULL, the IP address will be the local computer's address.

If nHostPort is 0, the port number will be the number of the first available port.

To connect to an SCP as an SCU, you must first create a DICOM Network object using LDicomNet::LDicomNet. Then call LDicomNet::Connect to establish the connection.

To use your computer as an SCP, you must first create a DICOM Network object using LDicomNet::LDicomNet. Then call LDicomNet::Listen to listen for incoming connection requests.

When an SCU calls this function, it generates an LDicomNet::OnAccept function call on the SCP.
