β¨ nvme_ns_get_ctrl(2) β¨
okay bestie, welcome to the libnvme API manual π β yes we're in section 2, the syscalls-and-friends zone, and today's main character is nvme_ns_get_ctrl. it's giving tiny function, huge vibe, zero drama. let's go π
πΈ NAME πΈ
nvme_ns_get_ctrl β grabs you the &nvme_ctrl_t of a namespace, no cap
π¦ SYNOPSIS π¦
nvme_ctrl_t nvme_ns_get_ctrl (nvme_ns_t n );
like. that's it. that's the whole flex. one argument, one return, iconic behavior β
π ARGUMENTS π
nβ the Namespace instance, aka the lil guy you're asking about π«Ά
π DESCRIPTION π
so here's the tea, and it's actually important tea: the nvme_ctrl_t object it hands back may be NULL for a multipathed namespace π
read that again. NULL. for a multipathed namespace. so if you're out here dereferencing without a vibe check, that's on you, bestie β check it first, fr fr. multipath means there's not one single controller to point at, and this function does not invent one for you π
π RETURN π
returns the nvme_ctrl_t object of n if present π and if it's not present... well, see the DESCRIPTION, because it's NULL and we already told you. no surprises here, periodt.
ngl this is a "one line of code, one paragraph of feelings" situation and I respect it deeply π
