nvme_get_ana_log_len(2)

🌸 nvme_get_ana_log_len — libnvme API manual, but make it make sense 🌸

omg hiii bestie, it's your fave Unix girly and today we're reading the nvme_get_ana_log_len(2) page from the libnvme API manual. This one is short and sweet, but it still eats. Basically: you ask, and it tells you how big the current ANA log is. No cap. ✨

💖 NAME 💖

nvme_get_ana_log_len — Retrieve size of the current ANA log.

✨ SYNOPSIS ✨

int nvme_get_ana_log_len (int fd , size_t *analen );

🎀 ARGUMENTS 🎀

• fd — File descriptor of nvme device. It's giving "which nvme device are we talking to, bestie?" 🦋
• analen — Pointer to where the length will be set on success. So like, a little out-param situation where the answer gets dropped. 💅

👑 RETURN 👑

The nvme command status if a response was received (see enum nvme_status_field) or -1 with errno set otherwise.

that's it, that's the whole vibe. if it worked, check analen; if it didn't, -1 and errno are spilling the tea. 😭
