STRUCT AUXTRACE_INDEX(9)

💅 struct auxtrace_index(9)

okay so bestie, welcome to the Kernel API Manual ✨ we're looking at struct auxtrace_index today and honestly? it's giving organizational queen 👑

🌸 NAME

struct auxtrace_index — the index of AUX area tracing events inside a perf.data file. that's it, that's the whole vibe 🎀

✨ SYNOPSIS

struct auxtrace_index {
    struct list_head        list;
    size_t nr;
    struct auxtrace_index_entry
entries[PERF_AUXTRACE_INDEX_ENTRY_COUNT];
 };

no cap, that's the struct verbatim 💖

🦋 Members

• list — links a bunch of arrays of entries together, like a little friend group of arrays 🫶
• nr — the number of entries. literally just the count, bestie 🔢
• entries — the array of entries themselves 👑
