NAME

       acct - turn accounting on or off

SYNOPSIS

       acct(file)
       char *file;

DESCRIPTION

       The system is prepared to write a record in an accounting file for each process as it terminates.  This call, with a null-terminated string
       naming an existing file as argument, turns on accounting; records for each terminating process are appended to  file.   An  argument  of  0
       causes accounting to be turned off.

       The accounting file format is given in acct(5).

SEE ALSO

       acct(5), sa(1)

DIAGNOSTICS

       On  error  -1  is  returned.   The file must exist and the call may be exercised only by the super-user.  It is erroneous to try to turn on
       accounting when it is already on.

BUGS

       No accounting is produced for programs running when a crash occurs.  In particular nonterminating programs are never accounted for.

       [EACCES]       The path name is not a regular file.

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

       [EFAULT]       The file points outside the process's allocated address space.

       [ELOOP]	      Too many symbolic links were encountered in translating the pathname.

       [EIO]	      An I/O error occurred while reading from or writing to the file system.
