get_executable_name(3)

✨ NAME ✨

okay so bestie, welcome to the get_executable_name(3) page from the Allegro manual 🌸 this one is all about getting the full path to the current executable, and it's part of the Allegro game programming library 👑

• get_executable_name — obtains the full path to the current executable. Allegro game programming library. 💅

🦋 SYNOPSIS 🦋

#include <allegro.h>

void get_executable_name(char *buf, int size);

💖 DESCRIPTION 💖

okay so what does it actually do? It fills buf with the full path to the current executable, writing at most size bytes. periodt. ✨

The way it finds that path is lowkey a whole journey: it generally comes from argv[0], but on Unix systems it tries to get the information from the /proc filesystem first, searching the directories specified in $PATH if necessary. If this fails too, it tries to find the executable name from the output of the ps command, using argv[0] only as a last resort if all other options fail. 😭 fr fr, detective mode.

Example:

char name[200];
...
get_executable_name(name, sizeof(name));
allegro_message("Running `%s'\n", name);

Allegro manual, version 4.4.3 — and the date slot is empty on this page, bestie, so no date to spill 🎀💖 that's the whole tea, periodt.
