The following table provides mapping for the Callback mechanism between the Legacy translator and Connect:

Callback Mechanism in Legacy Translator Corresponding Code for Connect
api_xvda_set_abort SetProgressCallback method of SPAIConverter class. Example: 
void myProgressCallbackFunction(double iProgress, SPAXBoolean& oAbort)
{
    printf("\rTranslation Progress : %.10f %%", iProgress*100.0);
    oAbort = 0; // setting oAbort to 1 will abort translation
    if(iProgress>0.1)
    oAbort = 1; 
}
int main(int argc, char *argv)
{
    SPAIDocument src(pszInputFile);
    if( strlen(pszInputFormat) > 0 )
    src.SetType(pszInputFormat);
    SPAIDocument dst(pszOutputFile);
    converter.SetProgressCallback((SPAIProgressCallback)myProgressCallbackFunction);
    converter.Convert(src, dst); 
}
