Example:

 
Copy Code
AT_ERRCOUNT errCount = 0 ;
HIG_REC_REDACTOR higRecRedactor = 0 ;
AT_INT user_data = 0 ;

IG_REC_redactor_create( &higRecRedactor ) ;
errCount = IG_REC_redactor_redacted_cb_set 
                          ( higRecRedactor, 
                            &on_redacted,
                            &user_data
                          ) ;
IG_REC_redactor_delete( higRecRedactor ) ; 

Remarks:

Use this function to install a callback to receive a notification after all match results for each page or text string are redacted.

The redactor owns all data supplied to this callback. To conserve system resources, all non-user callback data will be deleted after the callback returns. Callers that require access to callback data after the callback returns must duplicate and assume ownership of the copy.
