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 enhances the TDengine client wrapper library by implementing a comprehensive error hinting system. The primary goal is to improve the user experience during debugging by providing clear, context-specific suggestions when dynamic link libraries or their functions fail to load. This involves distinguishing between different types of loading failures and offering platform-specific troubleshooting steps, making it easier for users to resolve common setup and configuration issues.

Highlights

• New Error Hinting Mechanism: Introduced a new wrapperHint module to provide more descriptive and actionable error messages when the TDengine client driver or its functions fail to load.
• Improved Error Specificity: Error handling macros in wrapperFunc.c were updated to differentiate between the entire DLL/shared library failing to load and specific functions within a loaded library not being found, using TSDB_CODE_DLL_FUNC_NOT_LOAD.
• Platform-Specific Guidance: The new hinting system includes platform-specific error messages and common solutions for Linux and Windows operating systems, addressing typical shared library loading issues like file not found, permission denied, or corrupted files.
• Integration into Driver Loading: The showWrapperHint function is now called in wrapperDriver.c whenever there's a failure to load the TDengine driver or any of its required functions, providing immediate user feedback.

Code Review

This pull request introduces a valuable enhancement by adding hint messages for wrapper library errors, which will significantly improve the user experience when troubleshooting loading issues. The implementation is solid, introducing new files for hint logic and correctly integrating them. I've provided a few suggestions to enhance code quality and maintainability, such as using symbolic constants for error codes, improving documentation, and properly scoping helper functions. The introduction of the TSDB_CODE_DLL_FUNC_NOT_LOAD error code is also a positive change for more precise error reporting.
