| | 45 | The kernel maintains the following |
| | 46 | .Fa acct |
| | 47 | information structure for all |
| | 48 | processes. If a process terminates, and accounting is enabled, |
| | 49 | the kernel calls the |
| | 50 | .Xr acct 2 |
| | 51 | function call to prepare and append the record |
| | 52 | to the accounting file. |
| | 53 | .Bd -literal |
| | 54 | /* |
| | 55 | * Accounting structures; these use a comp_t type which is a 3 bits base 8 |
| | 56 | * exponent, 13 bit fraction ``floating point'' number. Units are 1/AHZ |

| | 93 | the name of the executed file (at most ten characters of it) |
