💖 CATCLOSE — the POSIX programmer's manual, bestie edition 💖

okay so real talk, this page is from the POSIX Programmer's Manual (CATCLOSE(3POSIX), section 3POSIX, if you're keeping track) and it's the whole saga of one tiny function that closes your message catalog. short king. iconic. let's get into it.

✨ PROLOG ✨

bestie, heads up before you get attached: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so pls consult the corresponding Linux manual page for the details of how Linux actually does it, or the interface may not be implemented on Linux at all. no cap, check first. 🫶

🌸 NAME 🌸

catclose — close a message catalog descriptor. that's it. that's the whole job. 💅

🎀 SYNOPSIS 🎀

#include <nl_types.h>

int catclose(nl_catd catd);

🦋 DESCRIPTION 🦋

so the catclose() function shall close the message catalog identified by catd. and listen — if a file descriptor is used to implement the type nl_catd, that file descriptor shall be closed too. like, it goes away. gone. closed. the way that it actually tidies up after itself?? we love a responsible function. 💜

👑 RETURN VALUE 👑

  • upon successful completion, catclose() shall return 0. slay. ✨
  • otherwise, -1 shall be returned, and errno set to indicate the error. 😭

🔥 ERRORS 🔥

the catclose() function may fail if:

  • EBADF — the catalog descriptor is not valid. bestie that descriptor is not real, it's giving fake. 💀
  • EINTR — the catclose() function was interrupted by a signal. rude of that signal tbh. 🙈
heads up: the following sections are informative. (that's the manual telling you the tea is optional reading from here on, but we're reading it anyway because we're thorough.) ⭐
