💅 gcov_info_is_compatible — a Kernel API Manual moment

gcov_info_is_compatible — check if profiling data can be added 🫶

---

✨ SYNOPSIS ✨

int gcov_info_is_compatible (struct gcov_info *info1 , struct gcov_info
*info2 );

like, yes, that's the whole thing. no cap. 🎀

🦋 ARGUMENTS 🦋

• info1 — the first profiling data set 💖
• info2 — the second profiling data set 💖

two little data sets, just standing there, about to find out if they're compatible. main character energy fr fr.

👑 DESCRIPTION 👑

Returns non-zero if profiling data can be added, zero otherwise.

that's it. that's the whole description. she's a one-liner and she knows it 💅 so like — non-zero means "yes bestie, go ahead, add that data", and zero means "nope, these two are not it" 🙈
