acct - Enables and disables process accounting
char *path );
Specifies a pointer to the pathname of the file, or specifies
a null pointer.
The acct() function enables and disables UNIX process
accounting. When enabled, process accounting produces an
accounting record on behalf of each terminating process.
The path parameter specifies the pathname of the file to
which an accounting record is written. When the path
parameter is 0 (zero) or a null value, the acct() function
disables the accounting routine. If the path parameter
refers to a symbolic link, the acct() function writes
records to the file pointed to by the symbolic link. If
Network File System is installed on your system, the
accounting file can reside on another node. To ensure
accurate accounting, each node must have its own accounting
file, which can be located on any node in the network.
The calling process must have superuser privilege to
enable or disable process accounting.
Upon successful completion, the acct() function returns a
value of 0 (zero). Otherwise, a value of -1 is returned
and errno is set to indicate the error.
If the acct() function fails, errno may be set to one of
the following values: The calling process does not have
appropriate system privilege. The file named by the path
parameter does not exist. The file named by the path
parameter is not an ordinary file. Write permission is
denied for the named accounting file. The named file
resides on a read-only file system.
