ONSECURELINKREADY

#include "ltdic.h"

L_VOID pEXT_CALLBACK Your_Function(hNet, nError, pUserData)

This function is called when an ISCL or TLS secured connection is successfully established. This function is available in the PACS Imaging.

Parameters

HDICOMNET hNet

Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.

L_UINT32 nError

Error code. For a list of possible values, refer to Return Codes.

L_VOID * pUserData

Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.

Returns

None.

Comments

This function is called after the ISCL or TLS connection is successfully established. From this moment until the connection is closed, an application can securely send and receive data.
