Cancel Conversion Task

ComPDF Conversion SDK supports interrupting an ongoing conversion task through the cancel callback in CConvertCallback. When the cancel callback returns true, the current conversion task stops as soon as possible.

static bool Cancel(void)
{
    return false;
}

CConvertOption option = CPDF_DefaultConvertOption();

CConvertCallback callback = {0};
callback.cancel = Cancel;

CSDKErrorCode code = CPDF_StartPDFToWord(
    CPDF_TEXT("input.pdf"),
    CPDF_TEXT("password"),
    CPDF_TEXT("path/output.docx"),
    option,
    &callback);

If you need to cancel the conversion at a specific time, return true from Cancel based on external state.
