Parameter

Description

hNet

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

nChallenge

Value that represents the challenge code sent to the peer computer. This value is similar to a time stamp. This function will determine whether the response code in the nResponse parameter is a valid response for this challenge code.

nResponse

Value that represents the response code generated by the peer computer. This value is similar to a time stamp. This function will determine whether this response code is a valid response for the challenge code in the nChallenge parameter.

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 response code and challenge code match.

<> DICOM_SUCCESS

The response code and challenge code do not match.
