STRUCT ANNOTATED_DATA_TYPE(9)

💅 struct annotated_data_type(9) 💅

okay bestie, welcome to the Kernel API Manual page for struct annotated_data_type. This is the struct that's literally labeled Data type to profile, and we're gonna walk through every field like it's the group chat receipts. 💖

✨ NAME ✨

• struct annotated_data_type — Data type to profile

🎀 SYNOPSIS 🎀

here's the whole struct, copied exactly — no edits, no cap:

       struct annotated_data_type {
           struct rb_node node;
           struct annotated_member self;
           int nr_histograms;
           struct type_hist **histograms;
        };

yes, int nr_histograms; is right there in the synopsis too — don't let the Members list below make you forget it. 👀

🫶 Members 🫶

• node — RB-tree node for dso->type_tree
• self — Actual type information
• histograms — An array of pointers to histograms

🌸 Description 🌸

This represents a data type accessed by samples in the profile data. Lowkey iconic: it's the struct holding the data-type info that shows up in the profile data. Keep that vibe in mind. ✨
