EXPLAIN_TCSETATTR_OR_DIE(3)

💖 explain_tcsetattr_or_die(3) 💖

okay bestie, so this is a page from the Library Functions Manual, and it's about explain_tcsetattr_or_die — yes the name is a whole mood, and yes it does exactly what it says. sit down, get comfy, we're setting terminal attributes and being very dramatic about the errors. 🎀

✨ NAME ✨

explain_tcsetattr_or_die — set terminal attributes and report errors

like. it sets your terminal attributes. and if that goes badly?? it reports the errors. no cap. 🦋

---

🌸 SYNOPSIS 🌸

#include <libexplain/tcsetattr.h>
void explain_tcsetattr_or_die(int fildes, int options, const struct
termios *data);
int explain_tcsetattr_on_error(int fildes, int options, const struct
termios *data);

two functions, one header, zero chill. 💅

---

👑 DESCRIPTION 👑

the explain_tcsetattr_or_die function 🫶

okay so this one is used to call the tcsetattr(3) system call. and the way it does it is so extra: on failure, an explanation gets printed to stderr, obtained from the explain_tcsetattr(3) function, and then the process terminates by calling exit(EXIT_FAILURE). it does not come back. it does not pass go. it's giving final girl energy, fr fr. 💀

the explain_tcsetattr_on_error function ✨

same deal, this one is also used to call the tcsetattr(3) system call. on failure an explanation gets printed to stderr, obtained from the explain_tcsetattr(3) function — but this one still returns to the caller. it's the chill sibling. it says its piece and then comes back to hang out with you. 🌈

the arguments, bestie 🌸

• fildes — the fildes, exactly as to be passed to the tcsetattr(3) system call. no tweaking, no vibes-based editing, just hand it over as-is.
• options — the options, exactly as to be passed to the tcsetattr(3) system call. same rule, icon behavior only.
• data — the data, exactly as to be passed to the tcsetattr(3) system call. yes, exactly. yes, all three. periodt. 👑

---

⭐ RETURN VALUE ⭐

the explain_tcsetattr_or_die function only returns on success — see tcsetattr(3) for more information. on failure, it prints an explanation and exits, so like... it does not return. it's gone. it left the group chat. 😭

the explain_tcsetattr_on_error function always returns the value return by the wrapped tcsetattr(3) system call. always. she's reliable like that. 💜

---

🎀 EXAMPLE 🎀

the explain_tcsetattr_or_die function is intended to be used in a fashion similar to the following example:

explain_tcsetattr_or_die(fildes, options, data);

that's it. that's the whole example. short, sweet, slays. ✨
