  39 .Sh NAME
  40 .Nm acct
  41 .Nd enable or disable process accounting
  42 .Sh SYNOPSIS
  43 .Fd #include <unistd.h>
  44 .Ft int
  45 .Fn acct "const char *file"
  46 .Sh DESCRIPTION
  47 The
  48 .Fn acct
  49 call enables or disables the collection of system accounting
  50 records.
  51 If the argument
  52 .Fa file
  53 is a nil pointer, accounting is disabled.
  54 If
  55 .Fa file
  56 is an
  57 .Em existing
  58 pathname (null-terminated), record collection is enabled and for
  59 every process initiated which terminates under normal
  60 conditions an accounting record is appended to
  61 .Fa file .
  62 Abnormal conditions of termination are reboots
  63 or other fatal system problems.
  64 Records for processes which never terminate can not be
  65 produced by
  66 .Fn acct .
  67 .Pp
  68 For more information on the record structure used by
  69 .Fn acct ,
  70 see
  71 .Pa /usr/include/sys/acct.h
  72 and
  73 .Xr acct 5 .
  74 .Pp
  75 This call is permitted only to the super-user.
  76 .Sh NOTES
  77 Accounting is automatically disabled when the file system the
  78 accounting file resides on runs out of space; it is enabled when
  79 space once again becomes available.
  80 .Sh RETURN VALUES
  81 On error -1 is returned.
  82 The file must exist and the call may be exercised only by the super-user.
