FILELUOPEN(3)

✨ NAME ✨

okay so fileluopen() — opens a file given a logical unit number. This is FILELUOPEN(3) from Schily's LIBRARY FUNCTIONS, and we're gonna get you comfy with it, bestie 💖

🌸 SYNOPSIS 🌸

FILE *fileluopen(lu, modes)
int lu;
char *modes;

🦋 DESCRIPTION 🦋

fileluopen() makes an object of type FILE, suitable for use with fileread(), putc(), etc. It's giving "build me a FILE handle and slay" ✨

• lu — the logical unit number assigned by the kernel when it opens a file. LUs are not usually visible, lowkey hidden from view, although several routines require LUs as arguments, and fdown() may be used to map a FILE object to a corresponding LU number. iykyk 🫶
• modes — a string encoding the modes of the file, just as for fileopen(), except that the 'c' and 't' options are not allowed. Not negotiable, bestie 💅

🎀 RETURNS 🎀

Returns the FILE value. That's it, that's the return 💖
