PARENT(3PVM)

✨ PARENT(3PVM) ✨

okay bestie, gather round 💖 this is pvm_parent from PVM Version 3.4, and it's literally the "who's your parent" of the PVM world. Like, every process has a origin story and this function is the one that spills the tea 🫖

---

🎀 NAME 🎀

pvm_parent — returns the tid of the process that spawned the calling process.

it's giving "who brought me into this world" energy and honestly? iconic.

---

🌸 SYNOPSIS 🌸

C

int tid = pvm_parent( void )

Fortran

call pvmfparent( tid )

---

🦋 PARAMETERS 🦋

• tid — an Integer. It hands you back the task identifier of the parent of the calling process. BUT — and this is the plot twist — if the calling process was not created with pvm_spawn, then tid = PvmNoParent. no cap. 🫶

---

💅 DESCRIPTION 💅

So pvm_parent returns the tid of the process that spawned the calling process. Simple. Elegant. Main character behaviour. 👑

And if the calling process was not created with pvm_spawn? Then tid gets set to PvmNoParent. That's the whole vibe check. periodt. ✨

---

🌈 EXAMPLES 🌈

C:

tid = pvm_parent();

Fortran:

CALL PVMFPARENT( TID )

look at you go, writing code 💖

---

💀 ERRORS 💀

Here's the one error condition that pvm_parent can throw back at you:

• PvmNoParent — the calling process was not created with pvm_spawn. so yeah, no parent, no tid, sad little orphan arc 😭
• PvmSysErr — can't contact local pvmd. the pvmd ghosted you fr fr 🙈

ngl if you're seeing PvmSysErr something is deeply wrong with your local daemon situation. not a vibe.
