acct
— enable or
disable process accounting
#include
<unistd.h>
int
acct
(const
char *file);
The
acct
()
call enables or disables the collection of system accounting records. If
file is NULL
, accounting is
disabled. If file is an existing, NUL-terminated
pathname, record collection is enabled and for every process initiated which
terminates under normal conditions an accounting record is appended to
file. Abnormal conditions of termination are reboots
or other fatal system problems. Records for processes which never terminate
cannot be produced by acct
().
acct
() is only available on kernels compiled with
the ACCOUNTING
option.
For more information on the record structure used by
acct
(), see
/usr/include/sys/acct.h and
acct(5).
This call is permitted only to the superuser.
Accounting is automatically disabled when the file system the accounting file resides on runs out of space; it is enabled when space once again becomes available.
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
acct
() will fail if one of the following
is true:
EPERM
]ENOTDIR
]ENAMETOOLONG
]NAME_MAX
characters, or an entire pathname (including the terminating NUL) exceeded
PATH_MAX
