💖 MPI_Errhandler_fromint(3) 💖

okay so bestie, welcome to the MPI manual, and today's main character is MPI_Errhandler_fromint — she converts an integer handle to MPI_Errhandler. that's it. that's the whole job. and she does it flawlessly. ✨

🌸 NAME 🌸

MPI_Errhandler_fromint — converts an integer handle to MPI_Errhandler. no cap, it's literally right there in the name. 🎀

🦋 SYNOPSIS 🦋

MPI_Errhandler MPI_Errhandler_fromint(int errhandler)

like. one line. one function. she's not doing too much, she's just doing it right. 💅

🍓 INPUT PARAMETERS 🍓

  • errhandler — the errhandler (integer). yeah bestie it's an integer, that's the whole point, we're turning an integer into an MPI_Errhandler. int in, errhandler out. glow up. 🫶

🔥 THREAD AND INTERRUPT SAFETY 🔥

okay so this part actually matters, so listen up:

This routine is thread-safe. what that means is you can hit it from multiple threads at the same time and you do not need to bring your own user-provided thread locks. she handles herself. no chaperone needed. 👑

BUT. ⚠️ The routine is not interrupt safe. and like, typically that's because of memory allocation routines such as malloc or other non-MPICH runtime routines that are themselves not interrupt-safe. so it's not her fault fr fr, it's the company she keeps. 😭

bestie. thread-safe ≠ interrupt-safe. do not conflate them, i am begging. 🙈

💜 sign-off 💜

k that's the whole page, you ate that. go forth and convert your integers, bestie. 🌈
