ExtractAsyncData Method

Extracts user data from the DC signing service response.

Syntax

ANSI (Cross Platform)
char* ExtractAsyncData(const char* lpszAsyncReply);

Unicode (Windows)
LPWSTR ExtractAsyncData(LPCWSTR lpszAsyncReply);
- (NSString*)extractAsyncData:(NSString*)asyncReply;
#define MID_PDFSIGNER_EXTRACTASYNCDATA 3

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PDFSigner_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.

The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to completion async stage.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
