zfcp_unit_add(9)

🎀 NAME 🎀

Hey bestie, this is zfcp_unit_add(9) from the Kernel API Manual — and its whole job is: add unit to unit list of a port. 💅 Periodt.

✨ SYNOPSIS ✨

The function signature is giving very specific spacing energy, so here it is exactly:

int zfcp_unit_add (struct zfcp_port *port , u64 fcp_lun );

💅 ARGUMENTS 💅

• port — pointer to port where unit is added. 🫶 Like, the port that's getting the new unit.
• fcp_lun — FCP LUN of unit to be added. 🔥 That's the FCP LUN identifier, no cap.

🔥 RETURN 🔥

• 0 success. That's the listed return vibe, bestie. ✨

🦋 DESCRIPTION 🦋

Okay so what does it actually do? It sets up some unit internal structures and creates sysfs entry. Literally that. Internal structures get set up, sysfs entry gets created — main character energy only. 💖

🌈 SEE ALSO 🌈
