💖 netlbl_domhsh_getentry(9) 💖

okay bestie, this one is from the Kernel API Manual, and it's literally the “get an entry out of the domain hash table” function. no cap, it's giving lookup energy ✨

🌸 NAME 🌸

netlbl_domhsh_getentry — get an entry from the domain hash table 🎀

🦋 SYNOPSIS 🦋

struct netlbl_dom_map * netlbl_domhsh_getentry (const char *domain , u16
       family );

🎀 ARGUMENTS 🎀

• domain — the domain name to search for, bestie 🔍
• family — address family, fr fr

🔥 DESCRIPTION 🔥

so it looks through the domain hash table, searching for an entry that matches domain, with address family family, and then returns a pointer to a copy of the entry or NULL. that's the whole vibe 💅

⚠️ important caveat, no skipping: the caller is responsible for ensuring that rcu_read_[un]lock is called. that's on you, bestie — don't forget it 😭
