From 0f1a22174fc7c6a0767617974640d521074174d5 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 28 Mar 2026 06:53:37 +0000 Subject: libreboot-utils: unified error handling i now use a singleton hook function per program: nvmutil, mkhtemp and lottery call this at the startup of your program: (void) errhook(exit_cleanup); then provide that function. make it static, so that each program has its own version. if you're writing a program that handles lots of files for example, and you want to do certain cleanup on exit (including error exit), this can be quite useful.
