find_tool_events(9)

okay so this is find_tool_events(9), and yes bestie, it's from the Kernel API Manual — she's got a very specific job and she's gonna do it. 💅

🌸 NAME 🌸

find_tool_events — search for the pressence (that's the page's spelling, iykyk) of tool events in metric_list. Think of it like a vibe check for tool events, except the guest list is metric_list. 🎀

✨ SYNOPSIS ✨

void find_tool_events (const struct list_head *metric_list , bool
       tool_events[TOOL_PMU__EVENT_MAX] );

That's a void return, so there's no return value to catch — periodt. 💖

🎀 ARGUMENTS 🎀

• metric_list — the list you're taking metrics from. This is the source pile, bestie. 🫶
• tool_events — an array of false values. The indices that correspond to tool events get set to true if that tool event is found. So it's a little treasure map of trues and falses. 🌈
