obtained from the
explain_acct(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The
explain_acct_on_error function is used to call the
acct(2)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_acct(3) function, but still returns to the
caller.

system call.
RETURN VALUE¶

acct(2) for more information. On failure, prints an explanation and
exits, it does not return.
The
explain_acct_on_error function always returns the value return by the
wrapped
acct(2) system call.
EXAMPLE¶
