KNET_SEND(3)

💌 KNET_SEND(3) — the send-some-data-to-your-knet-nodes era 💌

okay bestie, gather round, because this is knet_send, straight out of the Kronosnet Programmer's Manual. yes the whole manual. we're doing this. 🦋

---

✨ NAME ✨

knet_send — literally just send data to knet nodes. that's it. that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

#include <libknet.h>

ssize_t knet_send(
    knet_handle_t  knet_h,
    const char    *buff,
    const size_t   buff_len,
    const int8_t   channel
);

look at her. four little args. absolute icon behavior. 🎀

---

💖 DESCRIPTION 💖

knet_send 💫

• knet_h — pointer to knet_handle_t. your handle, your main character, the whole vibe.
• buff — pointer to the buffer of data to send. the goods. the payload. the moment. ✨
• buff_len — length of data to send. how much of the goods we're shipping.
• channel — channel number. pick your lane, babe. 🛣️

---

🔥 RETURN VALUE 🔥

ngl this is the part where the manpage gets a lil unhinged and we respect it fr fr:

knet_send is a commodity function to wrap iovec operations around a socket. It returns a call to writev(2).

so yeah, it's a lil wrapper bestie, and what you get back is whatever writev(2) hands you. 💀
