ACCT(2) OpenBSD Programmer's Manual ACCT(2)NAMEacct - enable or disable process accounting
SYNOPSIS
#include <unistd.h>
int
acct(const char *file);
DESCRIPTION
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.
NOTES
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.
RETURN VALUES
On success, zero is returned. Otherwise, -1 is returned and errno is set
to indicate the error.
ERRORSacct() will fail if one of the following is true:
[EPERM] The caller is not the superuser.
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG]
A component of a pathname exceeded {NAME_MAX} characters,
or an entire path name exceeded {PATH_MAX} characters.
[ENOENT] The named file does not exist.
[EACCES] Search permission is denied for a component of the path
prefix, or the path name is not a regular file.
[ELOOP] Too many symbolic links were encountered in translating the
pathname.
[EROFS] The named file resides on a read-only file system.
[EFAULT] file points outside the process's allocated address space.
[EIO] An I/O error occurred while reading from or writing to the
file system.
