NAME

       explain_settimeofday_or_die - sets system time and report errors

SYNOPSIS

       #include <libexplain/settimeofday.h>
       void explain_settimeofday_or_die(const struct timeval *tv, const struct timezone *tz);
       int explain_settimeofday_on_error(const struct timeval *tv, const struct timezone *tz);

DESCRIPTION

       The  explain_settimeofday_or_die function is used to call the settimeofday(2) system call.
       On  failure  an   explanation   will   be   printed   to   stderr,   obtained   from   the
       explain_settimeofday(3)   function,   and   then   the   process   terminates  by  calling
       exit(EXIT_FAILURE).

       The explain_settimeofday_on_error function is used  to  call  the  settimeofday(2)  system
       call.   On   failure  an  explanation  will  be  printed  to  stderr,  obtained  from  the
       explain_settimeofday(3) function, but still returns to the caller.

       tv      The tv, exactly as to be passed to the settimeofday(2) system call.

       tz      The tz, exactly as to be passed to the settimeofday(2) system call.

RETURN VALUE

       The explain_settimeofday_or_die function only returns on success, see settimeofday(2)  for
       more information. On failure, prints an explanation and exits, it does not return.

       The  explain_settimeofday_on_error function always returns the value return by the wrapped
       settimeofday(2) system call.

EXAMPLE

       The explain_settimeofday_or_die function is intended to be used in a  fashion  similar  to
       the following example:
              explain_settimeofday_or_die(tv, tz);
