tomoyo_memory_ok(9)

🌸 NAME 🌸

ok so listen — tomoyo_memory_ok is the vibe-check function for your memory quota 💅 it literally checks whether you're still within your allotment, no cap.

✨ SYNOPSIS ✨

bool tomoyo_memory_ok (void *ptr );

🎀 ARGUMENTS 🎀

• ptr — a pointer to memory that's already been allocated, bestie. that's it, that's the whole input 🫶

🦋 DESCRIPTION 🦋

so here's the tea: this function returns true on success and false otherwise. periodt.

more specifically (because we love specifics), it returns true if ptr is not NULL and the quota has not been exceeded — and false otherwise. not me being obsessed with a two-condition check 😭 but like, that's genuinely all it does, iykyk.

💀 important: the caller holds the tomoyo_policy_lock mutex. like, you are holding it, not this function. so don't come for me if you forgot to grab it first — that's on you, bestie. lock it before you call it, fr fr.
