A five-star bake. Worth schmearing, sharing, saving.
Summary
The article discusses the implementation of generic containers in C programming, specifically focusing on a 'Maybe' type for safe division. It provides code examples for defining and using the 'Maybe' type to handle division operations safely, ensuring no division by zero occurs. The article is technical and aimed at programmers familiar with C.

static maybe(int) divide(int a, int b) { return (b != 0) ? maybe_just(int, a / b) : maybe_nothing(int); }
#define maybe(T) struct maybe_##T { bool ok; T value; }
In the caller, we can then check whether the value exists or not.
