What are some common errors in C extensions?

What are some common errors I might encounter when writing C extensions?

Some common errors include memory leaks, incorrect data types, and improper use of the Python C API.

Can you explain what a memory leak is in this context?

A memory leak occurs when allocated memory is not properly released, leading to increased memory usage over time.

How can I avoid these memory leaks?

You can avoid memory leaks by ensuring that every allocated memory block is freed after use and using tools like Valgrind.

What about type errors? How do they happen?

Type errors often occur when the data types expected by the C extension do not match those passed from Python.
