GSIZE(3PVM)

💖 GSIZE(3PVM) 💖

ok so this is pvm_gsize from PVM Version 3.4 — it lives in section 3PVM and it's literally the "how many of us are in this group rn" function. bestie, it's giving headcount. 🫶

---

✨ NAME ✨

pvm_gsize — returns the number of members presently in the named group. that's it, that's the whole job. 👑

---

🌸 SYNOPSIS 🌸

C version:

int size = pvm_gsize( char *group )

Fortran version:

call pvmfgsize( group, size )

---

🎀 PARAMETERS 🎀

• group — character string, the group name of an existing group. gotta be a real one, not a vibe.
• size — integer that comes back holding the number of members presently in the group. if it's less than zero, that's an error, no cap. 💀

---

🦋 DESCRIPTION 🦋

so pvm_gsize returns the size of the group named group. if there's an error, size will be negative. that's the whole tea.

and here's the important part, bestie — groups can change dynamically in PVM 3.0, so this routine can only guarantee to return the instantaneous size of a given group. like, the size at that exact moment. screenshot energy, not livestream energy. 📸

---

🌈 EXAMPLES 🌈

C:

size = pvm_gsize( "worker" );

Fortran:

CALL PVMFGSIZE( 'group2', SIZE )

---

⚠️ ERRORS ⚠️

these error conditions can be returned by pvm_gsize:

• PvmSysErr — pvmd was not started or has crashed. rip, the daemon ghosted you. 😭
• PvmBadParam — giving an invalid group name. wrong name, wrong vibe, rejected. 🙈

---

👀 SEE ALSO 👀

• pvm_joingroup(3PVM) — go join the group first, then come back and count yourselves. 🫶

---

that's the whole page, bestie — stay slay, count your group members, and never trust a size you measured five minutes ago ✨
