libnvme_get_subsystem(9)

okay so welcome to libnvme_get_subsystem(9) from the libnvme API manual — the function that pulls up a subsystem object and is honestly kind of iconic 💅✨

✨ NAME ✨

libnvme_get_subsystem — returns struct libnvme_subsystem object. That’s the whole assignment, bestie 🫶

🌸 SYNOPSIS 🌸

int libnvme_get_subsystem (struct libnvme_global_ctx *ctx , struct libnvme_host *h , const char *name , const char *subsysnqn , struct libnvme_subsystem **s );

🎀 ARGUMENTS 🎀

Here’s the cast of characters — every single one matters, no skipping:

• ctx — a struct libnvme_global_ctx object. The global-context main character 🌍
• h — a struct libnvme_host object. The host in question 🏠
• name — name of the subsystem (may be NULL). Yes, NULL is allowed, she’s flexible 💁‍♀️
• subsysnqn — the subsystem NQN. Say it with your chest 🔥
• s — a struct libnvme_subsystem object. The subsystem object itself 🦋

💅 DESCRIPTION 💅

It returns a struct libnvme_subsystem object in h based on name (if present) and subsysnqn, or creates one if it’s not found. That’s the tea ☕✨
