💅 genlmsg_put(9) — like, the kernel API manual bestie 🎀

like, the whole job. that's it. that's the vibe. 💖

🦋 SYNOPSIS 🦋

void * genlmsg_put (struct sk_buff *skb , u32 portid , u32 seq , const
struct genl_family *family , int flags , u8 cmd );

✨ ARGUMENTS ✨

  • skb — socket buffer holding the message. it's the little container your message is chillin' in 🫶
  • portid — netlink portid the message is addressed to. iykyk, it's who you're sending it to 💌
  • seq — sequence number (usually the one of the sender). lowkey just keep track of it, okay? 🔢
  • family — generic netlink family. the fam. the whole group chat 👑
  • flags — netlink message flags. the little toggles that change how it behaves ⚙️
  • cmd — generic netlink command. which thing you're actually asking for 🎯
