hwlocality..._reporting(3)

This is the Library Functions Manual page for hwlocality..._reporting(3), aka the one about API error reporting — and bestie, it’s short but important. 💅

💖 NAME 💖

hwlocality_api_error_reporting — Error reporting in the API ✨

✨ SYNOPSIS ✨

🌸 Detailed Description 🌸

Okay so most functions in the hwloc API return an integer value. Unless the docs for a specific function say otherwise, they return 0 on success and -1 on error. Functions that return a pointer type return NULL on error. No cap. 🫶

errno will be set to a meaningful value whenever possible. That includes the usual EINVAL when invalid function parameters are passed or ENOMEM when an internal allocation fails. Some specific errno values are also used — for instance, for binding errors as documented in CPU binding. 👑

Some modules describe the return values of their functions in their introduction, for instance in The bitmap API. 🦋
