UMAD_GET_CAS_NAMES(3)

✨ UMAD_GET_CAS_NAMES ✨

okay bestie, welcome to the umad_get_cas_names page from the OpenIB Programmer's Manual 💅 this one's short and sweet, which honestly? iconic. we're gonna get you a list of your InfiniBand device names and you're gonna slay.

🌸 NAME 🌸

umad_get_cas_names — get the list of available InfiniBand device names 💖

🎀 SYNOPSIS 🎀

#include <infiniband/umad.h>

int umad_get_cas_names(char cas[][UMAD_CA_NAME_LEN], int max);

🦋 DESCRIPTION 🦋

okay so here's the vibe: umad_get_cas_names() fills the cas array with up to max local IB devices — that's CAs, channel adapters, the whole crew — and it drops their names in there. 👑

the argument cas is a character array with max entries, and each one of those entries holds UMAD_CA_NAME_LEN characters. no cap. so like, max slots, UMAD_CA_NAME_LEN chars per slot, that's the shape of it 🫶

that's literally the whole function. she's simple. she's efficient. she ate. ✨

⭐ RETURN VALUE ⭐

umad_get_cas_names() comes back with a non-negative value that equals the number of entries she filled in for you 💖

...or -1 on errors 😭 which is giving "something went wrong bestie" energy. check your inputs, king.
