LDicomNet::GetChallengeISCL

#include "ltdic.h"

virtual L_UINT32 LDicomNet::GetChallengeISCL(nChallenge, nParameter)

L_UINT64 *nChallenge;	pointer to a variable
L_UINT64 nParameter;	key

Generates a random number. This function is available in the PACS Imaging toolkits.

Parameter	Description
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.

Returns

DICOM_SUCCESS	The generation of the random number was successful.
<> DICOM_SUCCESS	The generation of the random number was not successful.

Comments

The generation of a random number can use a pool of random (or pseudo-random) data. If the pool is empty, the GetChallenge function may fail. In this case, try to call GetChallenge later in the application, when some random data has been added to the pool.
