NAME
     acct - enable or disable process accounting

SYNOPSIS
     #include <unistd.h>

     int acct(const char *path);

DESCRIPTION
     acct() enables or disables the system process accounting routine. If
     the routine is enabled, an accounting record will be written in an
     accounting file for each process that terminates. The termination of a
     process 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 process cal-
     ling acct() must be superuser.

     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 not equal to (char *)NULL
     and no errors occur during the system call. It is disabled if path is
     (char *)NULL and no errors occur during the system call.

     acct() will fail if one or more of the following apply:

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

     EBUSY         An attempt is being made to enable accounting using the
                   same file that is currently being used.

     EFAULT        path points to an illegal address.

     ELOOP         Too many symbolic links were encountered in translating
                   path.

     ENAMETOOLONG  The length of the path argument exceeds PATHMAX or the
                   length of a path component exceeds NAMEMAX.

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

     ENOENT        One or more components of the accounting file pathname
                   do not exist.

     EPERM         The effective user of the calling process is not
                   superuser.

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

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