ACCT(2)              INTERACTIVE UNIX System              ACCT(2)



          NAME
               acct - enable or disable process accounting

          SYNOPSIS
               int acct (path)
               char *path;

          DESCRIPTION
               acct is used to enable or disable the system process
               accounting routine.  If the routine is enabled, an account-
               ing record will be written on an accounting file for each
               process that terminates.  Termination can be caused by one
               of two things: an exit call or a signal [see exit(2) and
               signal(2)].  The effective user ID of the calling process
               must be super-user to use this call.

               path points to a pathname naming the accounting file.  The
               accounting file format is given in acct(4).

               The accounting routine is enabled if path is non-zero and no
               errors occur during the system call.  It is disabled if path
               is zero and no errors occur during the system call.

               acct will fail if one or more of the following is true:

               [EPERM]        The effective user of the calling process is
                              not super-user.

               [EBUSY]        An attempt is being made to enable accounting
                              when it is already enabled.

               [ENOTDIR]      A component of the path prefix is not a
                              directory.

               [ENOENT]       One or more components of the accounting file
                              path name do not exist.

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

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

               [EFAULT]       Path points to an illegal address.

          SEE ALSO
               exit(2), signal(2), acct(4).

          DIAGNOSTICS
               Upon successful completion, a value of 0 is returned. Other-
               wise, a value of -1 is returned and errno is set to indicate
               the error.
