LOADFIRMWARE(9)

🎀 NAME 🎀

loadfirmware — load a firmware file from the filesystem

Hiii bestie 💖 welcome to LOADFIRMWARE(9), straight outta the Kernel Developer's Manual. This one is literally about loading a firmware file from the filesystem, and it's giving "small function, important job" energy ✨

---

✨ SYNOPSIS ✨

#include <sys/device.h>

int
loadfirmware(const char *filename, u_char **buf, size_t *buflen);

---

🦋 DESCRIPTION 🦋

Okay so loadfirmware() loads a firmware from the file specified by filename, and it looks in the directory /etc/firmware 👀✨

Memory for the firmware is allocated using malloc(9) with type M_DEVBUF as need be, within a reasonable size limit. No cap, that's the whole vibe.

If it's no longer needed, the firmware buffer buf can be freed using free(9) with type M_DEVBUF 🧚💜

---

🌸 RETURN VALUES 🌸

If successful, buf is set to point to the allocation and buflen is set to the size of the firmware. Then loadfirmware() returns 0 — iconic, we love a zero return 💅✨

Otherwise, it returns an errno style error. Not slay, but useful 😭
