the suggest improvement

[RajeshC03]

Thank you for your contributions! The code structure and modularity are well-organized, making it easier to read and maintain. Function names are descriptive, and the separation of concerns is a good practice.

Here are some suggested improvements to enhance robustness and maintainability:

Error Handling:

Instead of calling die(), consider modifying it to return meaningful error codes. This allows the caller function to handle errors gracefully instead of immediately exiting.
Explicit Validation:

Add validation checks for hdr after reading it to ensure it conforms to expected values. This prevents potential issues due to unexpected data.
Memory Management:

Ensure all allocated memory is properly freed after use. Implementing a cleanup function or a structured error-handling path will help prevent memory leaks.
Unit Testing:

Consider adding tests that cover edge cases, including error scenarios. This will improve the reliability and robustness of the code.
