💖 KNET_HANDLE_GET_CHANNEL 💖

okay bestie, welcome to the Kronosnet Programmer's Manual page for knet_handle_get_channel(3) — yes that's the real name, the header up top got a lil truncated so we're saying it in full here, you're welcome 🫶

✨ NAME ✨

knet_handle_get_channel — figure out which channel a file descriptor is living on 💅

🌸 SYNOPSIS 🌸

#include <libknet.h>

int knet_handle_get_channel(
    knet_handle_t  knet_h,
    const int      datafd,
    int8_t        *channel
);

🦋 DESCRIPTION 🦋

okay so. knet_handle_get_channel is the function. it's giving "reverse lookup" energy — you hand it a datafd and it tells you the channel that fd belongs to. no cap 🔥

here's the cast of characters:

  • knet_h — pointer to knet_handle_t. the handle. the main character. 👑
  • datafd — the datafd you want the channel for. you're asking: "which channel is associated with this one?"
  • *channel — this is where the answer goes. it will contain the result. ✨

⭐ RETURN VALUE ⭐

  • 0 — slay 💅 success. and *channel will contain the result.
  • -1 — not slay 😭 error, and errno is set. also *channel content is meaningless, so like… don't look at it, it's not serving anything.
fr fr, on -1 the *channel value is meaningless — check errno instead, bestie. don't get played. 💀
