WARNING for HBTIP users ======================= Due to the excessive amount of problem reports and long known (and unfixed) problems and due to the non-trivial nature of internet protocols, this document _strongly recommends to avoid_ using this library in anything production or in fact anything more serious than simple test code for educational purposes. Please notice that even if something happens to work in some specific scenario, it's highly likely it's not a stable solution, nor is it a secure solution. The only reason hbtip hasn't been deleted altogether is compatibility with 3.0, xHarbour and existing projects, plus the fact there are still some low-level functions that do work fine (tip_MimeType()) or have no better replacement yet (tip_MailAssemble()). For internet protocol related tasks, the recommended and supported library is _hbcurl_, which is a thin wrapper over libcurl's 'easy' API. libcurl is a highly ubiquitious, very stable, actively and professionally developed, secure communications library: https://curl.haxx.se/libcurl/c/ hbcurl's functionality covers _all_ hbtip protocol classes, and it does offer support for several protocols besides these. If you're looking for all required static and dynamic libraries to use hbcurl, including OpenSSL and libssh2, both 32 and 64-bit. See this page about feature support and other details: https://github.com/vszakats/harbour-deps/ Usage examples found on the internet for other languages are most of the time directly usable with minor modifications in Harbour. You can find several working examples under the hbcurl tests directory as well. Live curl command-lines can also be converted into compilable/adaptable API code using the `--libcurl ` curl option. If you opt to use hbtip anyway, and find any problem with it (like very common SMTP or FTP incompatibilities with various live servers found on the internet), your best bet is to address the problem yourself. Patches of sufficent quality will be of course accepted.
