.Sh DESCRIPTION
|
|
The kernel maintains the following
|
|
.Fa acct
|
|
information structure for all
|
|
processes. If a process terminates, and accounting is enabled,
|
|
the kernel calls the
|
|
.Xr acct 2
|
|
function call to prepare and append the record
|
|
to the accounting file.
|
|
.Bd -literal

/*

* Accounting structures; these use a comp_t type which is a 3 bits base 8
|
|
* exponent, 13 bit fraction ``floating point'' number. Units are 1/AHZ

If a terminated process was created by an
|
|
.Xr execve 2 ,
|
|
the name of the executed file (at most ten characters of it)
|
|
is saved in the field
|
|
.Fa ac_comm
|
|
and its status is saved by setting one of more of the following flags in
|
|
.Fa ac_flag:
