Parameter

Description

hNet

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

nChallenge

Pointer to a variable to be updated with the random number generated in the callback. This number is similar to a time stamp.

nParameter

Value that indicates the current mutual authentication key.

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.

DICOM_SUCCESS

The generation of the random number was successful.

<> DICOM_SUCCESS

The generation of the random number was not successful.
