D'oh! I meant exit(3). Since I need to write this email, I'll take the
opportunity to quote man-pages(7):
STYLE GUIDE
...
Example programs and shell sessions
Manual pages may include example programs demonstrating how to

• For consistency, all example programs should terminate using
either of:
exit(EXIT_SUCCESS);
exit(EXIT_FAILURE);
