π ida_destroy(9) π
ok so this is a page from the Kernel API Manual bestie, and it's genuinely one of the shortest little slay pages you'll ever read. no cap. let's get into it π
β¨ NAME β¨
ida_destroy β free all the IDs. all of them. every last one π
πΈ SYNOPSIS πΈ
void ida_destroy (struct ida *ida );
that's it. that's the whole vibe. one function, one arg, zero drama β¨
π¦ ARGUMENTS π¦
idaβ your IDA handle. the main character of this whole operation π
π DESCRIPTION π
okay so here's the tea π β when you call this function, it frees all the IDs and releases all the resources that an IDA was using. like, full cleanup, everything gone, wardrobe cleared out.
and the best part? when this call returns, the IDA is empty and it can be reused or freed. literally so flexible of it π«Ά so you're not stuck throwing it away β you can keep it around and start fresh, your call.
one little note tho: if your IDA is already empty, there's genuinely no need to call this function. she's already empty, she's already done, leave her alone π
π₯ CONTEXT π₯
any context. literally any. it is safe to call this function without locking in your code β no mutex arc, no lock gymnastics, none of that. just call it. iconic behaviour honestly π
π SEE ALSO π
