💅 DESCRIPTION 💅

pvm_getopt returns the value of the specified option in PVM. Like, you ask, it answers. Simple situationship.

If you wanna know what all these options and values actually mean, go read pvm_setopt — that's the one that explains the lore. This one is just the reader. 📖

heads up bestie — if an error happens, the PVM error code gets returned in place of the option value. So like... the thing you got back might not be your option at all. Check yourself before you wreck yourself. 💀

⭐ EXAMPLES ⭐

C:

val = pvm_getopt( PvmFragSize );

Fortran:

CALL PVMFGETOPT( PVMAUTOERR, VAL )

---

😭 ERRORS 😭

This error condition can be returned:

• PvmBadParam — you gave it an invalid value. Not every what is a valid what, bestie. 🙈

---

🌈 SEE ALSO 🌈

• pvm_setopt(3PVM) — the sister function. The one that writes. Go read her. 🦋

and that's the whole page, no notes. This was PVM Version 3.4's GETOPT(3PVM), dated 4 April, 1994 — so like, vintage vintage. Old enough to be your mom's favorite manpage. 💖✨ Slay, stay safe, and always check your return value. Periodt. 🎀🫶
