💖 buffer_putlonglong(3) 💖

okay bestie, gather round — this is a page from the Library Functions Manual, and today's main character is buffer_putlonglong, a lil function that lives in libowfat. she's tiny, she's useful, she's giving quiet competence. 🎀

✨ NAME ✨

buffer_putlonglong — write a decimal ASCII representation of a signed long integer to buffer 🦋

🌸 SYNTAX 🌸

#include <libowfat/buffer.h>

int buffer_putlonglong(buffer* b,signed long long x);

two arguments, one int coming back, no drama. 💅

🫶 DESCRIPTION 🫶

So like. buffer_putlonglong is equivalent to passing the result of fmt_longlong to buffer_put. that's it. that's the whole vibe. ✨

you hand her a signed long long and she turns it into decimal ASCII text and drops it into the buffer. no cap, she's just out here doing the formatting-for-you so you don't have to. 🌈

😭 RETURN VALUE 😭

• 0 — everything is fine, we ate, we're slaying, no notes 💖
• -1 — error bestie, and she's setting errno on her way out 🙈

fr fr, if you get -1 go check errno immediately, don't just stand there. 👑

and that's the whole page, bestie!! this little cutie is buffer_putlonglong(3) from the Library Functions Manual — yes, the footer literally just says her name again, she's that iconic, no version number, no date, just vibes. 🎀✨💜
