NAME
	  acct - Enables and disables process accounting

     SYNOPSIS
	  int acct (
	       char *path );

     PARAMETERS
	  path Specifies a pointer to the pathname of the file,	or
	       specifies a null	pointer.

     DESCRIPTION
	  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 parame-
	  ter is 0 (zero) or a null value, the acct() function dis-
	  ables	the accounting routine.

	  If the path parameter	refers to a symbolic link, the acct()
	  function writes records to the file pointed to by the	sym-
	  bolic	link.

	  If Network File System is installed on your system, the
	  accounting file can reside on	another	node.  To ensure accu-
	  rate 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.

     RETURN VALUES
	  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.

     ERRORS
	  If the acct()	function fails,	errno may be set to one	of the
	  following values:

	  [EPERM]   The	calling	process	does not have appropriate sys-
		    tem	privilege.

	  [ENOENT]  The	file named by the path parameter does not
		    exist.

	  [EACCES]  The	file named by the path parameter is not	an
		    ordinary file.

	  [EACCES]  Write permission is	denied for the named account-
		    ing	file.

	  [EROFS]   The	named file resides on a	read-only file system.
