fd_install(9)

💅 fd_install(9) 💅

okay bestie, welcome to the Kernel API Manual page for fd_install(9) — the function that literally installs a file pointer in the fd array. no cap, that's the whole plot. 🎀

✨ NAME ✨

fd_install — install a file pointer in the fd array. that's it, that's the gig. 🦋

🌸 SYNOPSIS 🌸

void fd_install (unsigned int fd , struct file *file );

🎀 ARGUMENTS 🎀

• fd — file descriptor to install the file in. that's the slot, bestie. ✨
• file — the file to install. the main character being placed. 💖

🦋 DESCRIPTION 🦋

This consumes the "file" refcount, so callers should treat it as if they had called fput(file).

⚠️ refcount vibes: the reference gets consumed by this call, so act like you already did fput(file). don't forget, okay? 😭
