Summary of Changes

Hello @DuanKuanJun, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the user experience by implementing a new error hinting mechanism within the client wrapper. It provides context-aware and platform-specific troubleshooting suggestions when the TDengine native client library or its functions fail to load, thereby streamlining the diagnostic process for common installation and configuration problems.

Highlights

  • Enhanced Error Messages: Introduced a new wrapperHint module to provide detailed, platform-specific hints for common client loading failures, guiding users to troubleshoot issues more effectively.
  • Refined Error Code Handling: Modified error checking logic to differentiate between the entire client library failing to load and specific functions within a loaded library not being found, using distinct error codes for improved diagnostic accuracy.
  • Documentation Update: Updated the Chinese error code documentation (docs/zh/14-reference/09-error-code.md) to include 0x prefixes for error codes and improve text alignment, enhancing clarity.

Code Review

This pull request introduces hint messages for wrapper client errors, which is a great improvement for user experience. The implementation is mostly good, but I've found a few areas for improvement.
Specifically, there's some redundant logic in wrapperHint.c that causes duplicate hint messages to be printed. I've suggested a refactoring to consolidate this. There's also a minor issue in wrapperHint.h with a mismatched include guard comment, and a missing newline at the end of wrapperHint.c.
The changes in wrapperFunc.c to use a more specific error code and the documentation update in 09-error-code.md are both good improvements.
