✨ rxrpc_kernel_set_tx_length(9) ✨

okay so bestie, welcome to the Kernel API Manual — this page is all about rxrpc_kernel_set_tx_length(9), and we're gonna make it make sense. 💅

💖 NAME 💖

rxrpc_kernel_set_tx_length — Set the total Tx length on a call. periodt. 🎀

🦋 SYNOPSIS 🦋

void rxrpc_kernel_set_tx_length (struct socket *sock , struct rxrpc_call
       *call , s64 tx_total_len );

🌸 ARGUMENTS 🌸

• sock — The socket the call is on. that's the vibe check location 🫶
• call — The call to be informed. yes, we're telling this call something important 💌
• tx_total_len — The amount of data to be transmitted for this call. literally the total Tx length, no cap ✨

👑 DESCRIPTION 👑

So this function lets a kernel service set the total transmit length on a call. it's giving "let me tell you how much data is coming" energy. 💫

And because of that, it allows buffer-to-packet encrypt-and-copy to be performed. iconic behavior, honestly. 🔥

This function is primarily for use for setting the reply length, since the request length can be set when beginning the call. iykyk. 💅
