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.
