DESCRIPTION

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

       The explain_strdup_on_error function is used to call the strdup(3) system call. On failure
       an explanation will be printed to stderr, obtained from  the  explain_strdup(3)  function,
       but still returns to the caller.

       strdup(3) system call.
