There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

.Nd enable or disable process accounting

.Sh LIBRARY

|
.Lb libc
|
|
.Sh SYNOPSIS
|
|
.In unistd.h
|
|
.Ft int
|
|
.Fn acct "const char *file"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn acct
|
|
call enables or disables the collection of system accounting records.
|
|
If
|
|
.Fa file
|
|
is
|
|
.Dv NULL ,
|
|
accounting is disabled.
|
|
If
|
|
.Fa file
|
|
is an existing, NUL-terminated, pathname, record collection is enabled,
|
|
and for every process initiated which terminates under normal
|
|
conditions an accounting record is appended to
|
|
.Fa file .
|
|
Abnormal conditions of termination are reboots or other fatal system problems.
|
|
Records for processes which never terminate can not be
|
|
produced by
|
|
.Fn acct .
|
|
.Pp
|
|
For more information on the record structure used by
|
|
.Fn acct ,
|
|
see
|
|
.Pa /usr/include/sys/acct.h
|
|
and
|
|
.Xr acct 5 .
|
|
.Pp
|
|
This call is permitted only to the super-user.
|
|
.Sh NOTES
|
|
Accounting is automatically disabled when the file system the
|
|
accounting file resides on runs out of space; it is enabled when
|
|
space once again becomes available.
|
|
For this purpose,
|
|
.Fn acct
|
|
creates a kernel thread called
|
|
.Dq acctwatch .
|
|
.Sh RETURN VALUES
|
|
On success, zero is returned.
|
|
Otherwise, \-1 is returned and
|
|
.Va errno
|
|
is set to indicate the error.
|
|
.Sh ERRORS

|
|

characters.
