rte_port_fd.h(3)

💖 rte_port_fd.h 💖

okay bestie, welcome to the rte_port_fd.h page — that's the header from the Library Functions Manual, and it's literally all about the RTE Port FD Device. pull up a chair, we're getting into file-descriptor-based ports and it's giving very much "small header, big energy" ✨

🌸 NAME 🌸

rte_port_fd.h — no cap, that's the whole name, that's the whole vibe 🫶

---

✨ SYNOPSIS ✨

#include <stdint.h>
#include 'rte_port.h'

🎀 Data Structures

• struct rte_port_fd_reader_params
• struct rte_port_fd_writer_params
• struct rte_port_fd_writer_nodrop_params

🦋 Variables

• struct rte_port_in_ops rte_port_fd_reader_ops
• struct rte_port_out_ops rte_port_fd_writer_ops
• struct rte_port_out_ops rte_port_fd_writer_nodrop_ops

three structs, three ops variables, perfectly balanced, as all things should be 💅

👑 Detailed Description 👑

RTE Port FD Device — that's the main character energy of this whole header fr fr.

• fd_reader: an input port built on top of a valid non-blocking file descriptor 🔥
• fd_writer: an output port built on top of a valid non-blocking file descriptor 🔥

heads up bestie: both of those are built on a valid non-blocking file descriptor — that's literally the requirement, don't come at it with a blocking fd, it's not that girl 🙈

Definition in file rte_port_fd.h.
