🌈 xpaatexit(3) — NAME 🌈

okay so bestie, welcome to xpaatexit(3), a page from the SAORD Documentation, and it is short but it is important, so stay with me 💖

• XPAAtExit — installs an exit handler 🎀 that's it, that's the whole job, and honestly? icon behavior.

✨ SYNOPSIS ✨

#include <xpa.h>

void XPAAtExit(void);

look at that. no arguments. no return value. just vibes 💅

🦋 DESCRIPTION 🦋

so here's the tea: XPAAtExit() installs an exit handler using atexit() that runs XPAFree on all XPA access points. yes, all of them. every single one. she does not play favorites ✨

when is this lowkey a lifesaver? when Unix sockets are in the picture, bestie. if your program never makes an explicit call to XPAFree(), then the Unix socket file will not be deleted immediately — not without an atexit handler doing the cleanup for you. so like, the socket file just sits there. lingering. unbothered. 💀 XPAAtExit() is the friend who actually takes the trash out on the way down.

🙈 NB: do not make this call in a Tcl/Tk application. accessing the Tcl native file system after Tcl has shut down all file systems causes the Tcl/Tl program to crash. like, full-on crash. not cute. not the moment. please don't 🫶

and that's the whole page, babe 🌸 this was xpaatexit(3) from version 2.1.15, dated July 23, 2013 — oldie but a goodie, and she still ate. periodt. 💜👑
