acct -- enable or disable process accounting
Standard C Library (libc, -lc)
acct(const char *file);
The acct() system call enables or disables the collection of system
accounting records. If the argument file is a nil pointer, accounting is
disabled. If file is an existing pathname (null-terminated), 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().
For more information on the record structure used by acct(), see
<sys/acct.h> and acct(5).
This call is permitted only to the super-user.
Accounting is automatically disabled when the file system the accounting
file resides on runs out of space; it is enabled when space once again
On error -1 is returned. The file must exist and the call may be exercised
only by the super-user.
The acct() system call will fail if one of the following is true:
[EPERM] The caller is not the super-user.
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG] A component of a pathname exceeded 255 characters, or
an entire path name exceeded 1023 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
[EROFS] The named file resides on a read-only file system.
[EFAULT] The file argument points outside the process's allocated
[EIO] An I/O error occurred while reading from or writing to
the file system.
The acct() function appeared in Version 7 AT&T UNIX.
