Fix and enhance the error messages

[dqhntt]

Description

Improve the error messages along with some minor changes. 😊

• Update comments for clarity
• Add more information in the error messages
• Modify error messages for cases where the last error code is a success code
  • GetLastError returning 0 and dlerror returning null means that the previous operation was successful, not that the functions failed. This could happen if another API call resets the error code before it is checked.
  • References:
    • The Open Group - dlerror()
    • Microsoft Documentation - GetLastError()
    • Microsoft Documentation - System Error Codes (0-499)

Changes include

• Bugfix (non-breaking change that solves an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (change that is not backwards-compatible and/or changes current functionality)

Checklist

• I have assigned this PR to myself
• I have added at least 1 reviewer
• I have tested this code
• I have added sufficient documentation in the code

Hey @martin-olivier,

Glad you liked it! 😊

While I’d love to take a look, I’m afraid I’m not familiar with developing on Windows enough to offer my opinions on this.
