CK_ULONG_PTR pulPartLen
);
Parameters¶
hSession[in] session handle.
pEncryptedPart[in] pointer to the encrypted data part.
ulEncryptedPartLen[in] length of encrypted data in bytes.
pPart[in] pointer to the location which receives the recovered data part or NULL.
pulPartLen[in] pointer to the length of the recovered part buffer.
