Description

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

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

tp
The tp, exactly as to be passed to the ftime(3) system call.

Return Value

The explain_ftime_on_error function always returns the value return by the wrapped ftime(3) system call.
