acct Subroutine

AIX Version 4.3 Base Operating System and Extensions Technical Reference, Volume 1

acct Subroutine

Purpose

Enables and disables process accounting.

Library

Standard C Library (libc.a)

Syntax

int acct (Path)
char *Path;

Description

The acct subroutine enables the accounting routine when the Path parameter specifies the path name of the file to which an accounting record is written for each process that terminates. When the Path parameter is a 0 or null value, the acct subroutine disables the accounting routine.

If the Path parameter refers to a symbolic link, the acct subroutine causes records to be written to the file pointed to by the symbolic link.

If Network File System (NFS) is installed on your system, the accounting file can reside on another node.

Note: To ensure accurate accounting, each node must have its own accounting file. Although no two nodes should share accounting files, a node's accounting files can be located on any node in the network.

The calling process must have root user authority to use the acct subroutine.

Parameters

Path

Specifies a pointer to the path name of the file or a null pointer.

Return Values

Upon successful completion, the acct subroutine returns a value of 0. Otherwise, a value of -1 is returned and the global variable errno is set to indicate the error.

Error Codes

The acct subroutine is unsuccessful if one or more of the following are true:

EACCES	Write permission is denied for the named accounting file.
EACCES	The file named by the Path parameter is not an ordinary file.
EBUSY	An attempt is made to enable accounting when it is already enabled.
ENOENT	The file named by the Path parameter does not exist.
EPERM	The calling process does not have root user authority.
EROFS	The named file resides on a read-only file system.

If NFS is installed on the system, the acct subroutine is unsuccessful if the following is true:

ETIMEDOUT

The connection timed out.
