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);
