CCOS(3P)

🦋 CCOS(3P) — the POSIX Programmer's Manual one 🦋

okay bestie, quick vibe check: this is CCOS(3P), straight out of the POSIX Programmer's Manual. it's giving ✨official standards document✨ energy, and we're about to make it cute. buckle up. 💖

💅 PROLOG 💅

real talk first, no cap: this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the details on how Linux actually behaves, okay? 😭 or... the interface might not even be implemented on Linux at all. so like. check first. 🙈

🌸 NAME 🌸

ccos, ccosf, ccosl — the complex cosine functions. that's it, that's the name section, she's simple and she knows it. 👑

---

✨ SYNOPSIS ✨

#include <complex.h>

double complex ccos(double complex z);
float complex ccosf(float complex z);
long double complex ccosl(long double complex z);

three besties, three precisions. the way that C does this every single time 💀

🎀 DESCRIPTION 🎀

so here's the tea 🍓 — the functionality described on this reference page is aligned with the ISO C standard. and if there's any conflict between the requirements described here and the ISO C standard? that was unintentional, bestie. this volume of POSIX.1‐2017 defers to the ISO C standard. the ISO C standard is the main character here, this page is just supporting cast. 👑

and what do these functions actually do? they shall compute the complex cosine of z. periodt. that's the whole job. 🌈

---

🔥 RETURN VALUE 🔥

these functions shall return the complex cosine value. like, that's the whole return. she gives you the cosine. ate. 💅

---

💀 ERRORS 💀

No errors are defined. not one. zero. the error section said "not me, I'm booked and busy elsewhere." 🧚

also heads up: the following sections are informative — meaning they're the chill, non-normative ones. so don't come for them, they're just vibing. 😌

---

🦋 EXAMPLES 🦋

None. sorry bestie, no examples today. the example section is empty. it's giving minimalist. 🙈

---

🌸 APPLICATION USAGE 🌸

None. nothing to see here either. truly the "no thoughts, head empty" section. ✨

---

💖 RATIONALE 💖

None. no rationale provided. the reasoning? unknown. the vibes? immaculate. 🫶

---

🌈 FUTURE DIRECTIONS 🌈

None. the future is unwritten. lowkey iconic of them. ⭐

👑 SEE ALSO 👑

and also, from the Base Definitions volume of POSIX.1‐2017: <complex.h> 💜

(go read those, iykyk. cacos is the inverse-flavored cousin. family reunion. 🎀)

and that's the whole page, bestie!! 🫶 this one came from IEEE/The Open Group, dated 2017, and yes, the page you just read is CCOS(3P) — the complex cosine girlies' official manual page. go forth and compute that complex cosine. slay. 💖✨
