💖 ndelay_off(3) — the blocking-mode button, bestie 💖

Library Functions Manual ✨ yes we are literally in the library functions section, this is a libowfat moment, iykyk.

🎀 NAME 🎀

ndelay_off — put a file descriptor in blocking mode 🛑⏳

✨ SYNTAX ✨

okay so first you gotta invite the header in, no cap:

#include <libowfat/ndelay.h>

extern int ndelay_off(int fd);

that's it. that's the whole vibe. she's a function, she takes an int fd, she gives you back an int. 💅

🦋 DESCRIPTION 🦋

so ndelay_off does the thing where it puts a file descriptor into blocking mode. like, that's her whole job, that's her main character energy. 👑

and bestie, what does blocking actually mean? it means when you're reading from and writing to blocking network sockets, FIFOs or device files, the call will possibly not return immediately — it'll just sit there and wait on more input or buffer space for output. she's patient. she's not in a rush. she's giving "i'll get back to you when i feel like it" energy and honestly? iconic. 💀

not me just sitting in a syscall waiting for data like it's a situationship 😭

and if something goes wrong? if an error occurred, ndelay_off will return nonzero and set errno accordingly. so like, always check your return value, bestie, errno is literally telling you what happened. fr fr. 🙈

and that's the whole page, periodt ✨

this lil cutie came from the Library Functions Manual, and the page signs itself ndelay_off(3) at the bottom — no date stamp on this one, so we're just gonna vibe with it as-is. stay blocking (when you want to), bestie 🫶🌸💜
