Also, do y'all call main() in the if block or do you just put the code you want to run in the if block?

There are a lot of other helpful replies in this thread, so I won't add much, but I did find this reference, which you could read if you have a lot of free time. But I particularly liked reading this summary:

  • _start calls the libc __libc_start_main;
  • __libc_start_main calls the executable __libc_csu_init (statically-linked part of the libc);
  • __libc_csu_init calls the executable constructors (and other initialisatios);
  • __libc_start_main calls the executable main();
  • __libc_start_main calls the executable exit().
