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

73 | This call is permitted only to the super-user. | |
74 | .Sh NOTES | |
75 | Accounting is automatically disabled when the file system the | |
76 | accounting file resides on runs out of space; it is enabled when | |
77 | space once again becomes available. | |
