💅 icetDestroyMPICommunicator — IceT Reference, section 3 🎀

okay bestie, welcome to the manual page for icetDestroyMPICommunicator(3), part of the IceT Reference. this is the little cleanup queen of the MPI communicator world and she is so unbothered. let's get into it ✨

---

🌸 NAME 🌸

icetDestroyMPICommunicator — literally just deletes a MPI communicator. that's the whole job. no notes. 💖

---

🦋 Synopsis 🦋

so first things first, you gotta pull in the header, right? like:

#include <IceTMPI.h>

and then the function itself is giving:

void icetDestroyMPICommunicator(   IceTCommunicator   comm  );

she takes one argument, returns nothing, and minds her own business. icon behavior. 👑

---

✨ Description ✨

okay so here's the tea ☕ — icetDestroyMPICommunicator destroys an IceTCommunicator. that's it, that's the whole function.

once you call it, comm becomes invalid — like, do not touch it, do not pass it to your friends, do not look at it — and any memory or MPI resources that comm was holding onto get freed. gone. released. she said "I'm done carrying this" and honestly? same. 🫶

but here's the part that's actually kind of iconic: communicators are copied when they get attached to an IceT context. so if you made a context with an IceTCommunicator and that context is still out here living its life, you can still destroy the IceTCommunicator you used to make it. it is totally safe. no cap. the context keeps its own copy, so nothing breaks. slay. 💅

---

💀 Errors 💀

None. not a single one. she does not do errors. clean, flawless, unproblematic. ✨

---

🌈 Warnings 🌈

None. zero. nothing to warn you about. she's a good girl, your honor. 🎀

---

🙈 Bugs 🙈

okay so this is the one lil thing — all MPI errors are ignored. like, every single one. she just doesn't want to hear it. it's giving "la la la can't hear you" energy. so just know that going in, bestie. 😭
