ssh_request_set_data(9)

💅 ssh_request_set_data — the one where you point a request at your raw bytes

okay so bestie, welcome to ssh_request_set_data(9), straight out of the Kernel API Manual, section 9 ✨ (yes we're in the kernel-hacker part of the manual, section 9, the fun one 🧚)

---

🌸 SYNOPSIS 🌸

void ssh_request_set_data (struct ssh_request *r , u8 *ptr , size_t len
);

it's giving "three arguments, zero return value, maximum chaos" 💅 like the function literally hands you back nothing (void) and honestly? iconic.

---

🎀 ARGUMENTS 🎀

• r — the request you're setting the message data on 🫶 this is the main character of the whole operation.
• ptr — a pointer to the memory that's holding the message data 🍓 like, the actual bytes live over there, this just points at 'em.
• len — the length of that message data. how many bytes are we talking about, bestie? this number. 🔥

---

🦋 DESCRIPTION 🦋

so what it does is: it sets the raw message data buffer of the underlying packet to the buffer you specified ✨ super straightforward.

but here's the important part, and I need you to hear me on this one ngl:

it does NOT copy the actual message data. 🙈 all it does is set the buffer pointer and the length. that's it. the bytes stay exactly where they are and you better keep them alive, ok?

if you want more details on that, go check out ssh_packet_set_data — that's your girl for the deeper lore 💖
