DESCRIPTION

15       The explain_usleep_or_die function is used to call the usleep(3) system
16       call.  On  failure  an  explanation will be printed to stderr, obtained
17       from the explain_usleep(3) function, and then the process terminates by
18       calling exit(EXIT_FAILURE).
19
20       The explain_usleep_on_error function is used to call the usleep(3) sys‐
21       tem call. On failure an explanation will be printed to stderr, obtained
22       from the explain_usleep(3) function, but still returns to the caller.

32       the wrapped usleep(3) system call.
