local_add_negative(9)

💖 NAME 💖

okay so bestie, welcome to the local_add_negative(9) page from the Kernel API Manual — yes, that's the manual name, and this function is literally called local_add_negative, and it adds something then tells you if the result is negative. main character energy fr fr 🌸.

✨ SYNOPSIS ✨

bool local_add_negative (long i , local_t *l );

🎀 ARGUMENTS 🎀

• i — the integer value to add. that's it, that's the number going in 💅
• l — a pointer to type local_t. yes, local_t, not plain local — copy the type exactly, bestie 🫶

💫 DESCRIPTION 💫

so the way this works: it atomically adds i to l, then returns true if the result is negative, or false when the result is greater than or equal to zero. that's the whole description — no extra lore, just the atomic add and the true/false vibe check 🔥.
