| | 42 | .Sh SYNOPSIS |
| | 43 | .Fd #include <unistd.h> |
| | 44 | .Ft int |
| | 45 | .Fn acct "const char *file" |
| | 46 | .Sh DESCRIPTION |
| | 47 | The |
| | 48 | .Fn acct |
| | 49 | call enables or disables the collection of system accounting |
| | 50 | records. |
| | 51 | If the argument |
| | 52 | .Fa file |
| | 53 | is a nil pointer, accounting is disabled. |
| | 54 | If |
| | 55 | .Fa file |
| | 56 | is an |
| | 57 | .Em existing |
| | 58 | pathname (null-terminated), record collection is enabled and for |
| | 59 | every process initiated which terminates under normal |
| | 60 | conditions an accounting record is appended to |
| | 61 | .Fa file . |
| | 62 | Abnormal conditions of termination are reboots |
| | 63 | or other fatal system problems. |
| | 64 | Records for processes which never terminate can not be |
| | 65 | produced by |
| | 66 | .Fn acct . |
| | 67 | .Pp |
| | 68 | For more information on the record structure used by |
| | 69 | .Fn acct , |
| | 70 | see |

| | 72 | and |
| | 73 | .Xr acct 5 . |
| | 74 | .Pp |
| | 75 | This call is permitted only to the super-user. |
| | 76 | .Sh NOTES |
| | 77 | Accounting is automatically disabled when the file system the |
| | 78 | accounting file resides on runs out of space; it is enabled when |
| | 79 | space once again becomes available. |
| | 80 | .Sh RETURN VALUES |
| | 81 | .Rv -std acct |
| | 82 | The file must exist and the call may be exercised only by the super-user. |
