// Exit codes for SIPNET; most of the current uses of exit(1) should
// get better codes, which will appear here.
//
// Note for future: some codes typically have other meanings and should not be
// used here (except for 0 and 1, for which our meaning is the usual meaning).
// Some somewhat-standard codes in use:
// - 0-2, 126-165, and 255; see, e.g., https://tldp.org/LDP/abs/html/exitcodes.html
// - 64-78, see https://man7.org/linux/man-pages/man3/sysexits.h.3head.html
//
// The upshot here is that we should be a little sparing in our list of error codes.
typedef enum {
  EXIT_CODE_SUCCESS = 0,
  EXIT_CODE_FAILURE = 1, // generic failure
  // code 2 typically has a special meaning, see above
