💫 TOASCII 💫

ok bestie so this is a page from the POSIX Programmer's Manual, and the manual name is right there in the title — toascii, section 3P. Cute, right? 🎀

🌸 PROLOG 🌸

so like, heads up first: this manual page is part of the POSIX Programmer's Manual. But — and this is the important bit — the Linux implementation of this interface may differ (so pls go consult the corresponding Linux manual page for details on Linux behavior), or honestly the interface might not even be implemented on Linux at all. 🙈 no cap.

✨ NAME ✨

toascii — translate an integer to a 7-bit ASCII character

it's giving "i will simply make this a 7-bit ASCII character". iconic behavior. 💅

🦋 SYNOPSIS 🦋

#include <ctype.h>

int toascii(int c);

💖 DESCRIPTION 💖

ok so here's the tea: the toascii() function shall convert its argument into a 7-bit ASCII character. that's it. that's the whole job. lowkey a slay. ✨

👑 RETURN VALUE 👑

the toascii() function shall return the value (c &0x7f).

like literally just that. mask off the top bits and boom, 7-bit character, main character energy. 🫶

💀 ERRORS 💀

No errors are returned. not a single one. she's unproblematic fr fr. 😌

The following sections are informative.

🍓 EXAMPLES 🍓

None.

(no examples bestie. not one. we're working with vibes only here.) 💀

🌈 APPLICATION USAGE 🌈

ok so real talk: the toascii() function cannot be used portably in a localized application. so like, if your app is all localized and fancy, this is not the one. keep that in mind. 😭

🧚 RATIONALE 🧚

None.

⭐ FUTURE DIRECTIONS ⭐

heads up bestie 👀 — the toascii() function may be removed in a future version. so like... don't build your whole personality around it. 💅
