If I have operated correctly I obtain a 0x02FF (PTP_ERROR_IO) [decimal
767], but be aware I am not a C programmer so please review my code:

I changed

add_ptp_error_to_errorstack(device, ret, "LIBMTP_Get_Files_And_Folders(): could not get object handles.");

into

    char stError[255]="LIBMTP_Get_Files_And_Folders(): could not get object handles. ERROR CODE=";
    char stRet[12]="";
    sprintf(stRet, "%#010x\n", ret);
    strcat (stError,stRet);
    add_ptp_error_to_errorstack(device, ret, stError);

Is it correct?

Thanks,
Andrea
