✨ xs_local_send_request(9) ✨

ok so bestie, this is a page straight out of the Kernel API Manual and honestly? it's giving "small function, big responsibilities" 💅 we're talking about xs_local_send_request — the little guy that shoves your RPC request out the door of an AF_LOCAL socket. buckle up 🎀

🌸 NAME 🌸

xs_local_send_request — write an RPC request to an AF_LOCAL socket 🦋

✨ SYNOPSIS ✨

int xs_local_send_request (struct rpc_rqst *req );

🎀 ARGUMENTS 🎀

  • req — pointer to RPC request 👑 that's it, that's the whole argument list, she's low-maintenance fr fr

💖 DESCRIPTION 💖

okay so the whole vibe of this function is: you hand it a request, it tries to send it, and then it tells you how that went via its return value. no cap, that's the tea ☕ and here's the full breakdown of what those return values mean, because bestie you need to know which one you got:

  • 0 — slay! the request has been sent 💅✨ mission accomplished
  • EAGAIN — the socket was blocked 😭 please call again later to complete the request. it's not a no, it's a "not right now"
  • ENOTCONN — the caller needs to invoke connect logic then call again 🫶 so like, go make the connection happen first, then come back
  • other — some other error occurred, and the request was not sent 💀 big yikes, nothing went out
