libnvme_open(9)

💖 NAME 💖

okay so this is libnvme_open(9) — the page from the libnvme API manual that opens an nvme controller or namespace device. bestie, it's giving “welcome to the device-open era” ✨

🦋 SYNOPSIS 🦋

int libnvme_open (struct libnvme_global_ctx *ctx , const char *name ,
       int flags , struct libnvme_transport_handle **hdl );

🎀 ARGUMENTS 🎀

• ctx — the struct libnvme_global_ctx object. your whole context bestie 💅
• name — the basename of the device to open. yes, the basename 🫶
• flags — flags to pass to the underlying open(2) call, e.g. O_RDONLY or O_RDONLY | O_EXCL. exact flags, no improvising ✨
• hdl — the transport handle to return. this is the lil output slot 🔥

🌸 DESCRIPTION 🌸

okay so this will look for the handle in /dev/ and validate the name and filetype match linux conventions. no cap, that's the whole vibe check: it's finding the handle, checking the name, and checking the filetype against linux conventions 💖

⭐ RETURN ⭐

0 on success, negative error code otherwise. slay when it's 0, and when it's negative... well, that's your error code, bestie 😭
