gsm_send_packet(9)

💖 NAME 💖

okay bestie, welcome to gsm_send_packet(9) from the Kernel API Manual — this is the page for the function that sends a single packet. one packet. that’s the whole vibe. ✨

🌸 SYNOPSIS 🌸

int gsm_send_packet (struct gsm_mux *gsm , struct gsm_msg *msg );

like, that’s the signature, no cap. 🫶

🎀 ARGUMENTS 🎀

• gsm — the GSM Mux. your mux bestie. 💅
• msg — the packet to send. yes, that one. 📦

🦋 DESCRIPTION 🦋

okay so what it does: it takes the given packet, encodes it, and sends it out. encoded and sent out. it does not free any memory — none, zero, not a single byte. 😭 and the caller (that’s you, bestie) must hold the gsm tx lock. no lock, no send; it’s giving strict. 🔥
