Showpy Episode 5: Pointers from C to Python and Back

Here’s what’s going on in this tutorial:

• We will be embedding Python in a small C program
• For the sake of example, we will not use any third party wrappers around Python
• For the sake of example, we will not return the modified buffer and length, but rather modify it directly from Python, effectively “passing a pointer” back and forth
• For the sake of example, we will keep Python value/error checking at a minimum
