.Fn pidfile

creates a file containing the process ID of the caller program.
The pid file can be used as a quick reference if
the process needs to be sent a signal.
When the program exits, the pid file is removed automatically, unless
the program receives a fatal signal.
.Pp
If
.Ar path
is
.Dv NULL
or a plain basename (a name containing no directory components), the pid file
is created in the
.Pa /var/run
directory.
The file name has the form
.Pa /var/run/basename.pid .
If the
.Ar basename
argument is
The basename part is either the value of
.Ar path
if it was not
.Dv NULL ,
.Fn pidfile
will determine the program name and use that instead.
or the program name as returned by
.Xr getprogname 3
otherwise.
.Pp
The pid file can be used as a quick reference if
the process needs to be sent a signal.
When the program exits, the pid file will be removed automatically, unless
the program receives a fatal signal.
If
.Ar path
is an absolute or relative path (i.e. it contains the
.Sq /
character),
the pid file is created in the provided location.
.Pp
Note that only the first invocation of
.Fn pidfile
causes a pid file to be written; subsequent invocations have no effect
unless a new
.Ar basename
.Ar path
is supplied.
If called with a new
.Ar basename ,
.Ar path ,
.Fn pidfile
will remove the old pid file and write the new one.

.Dt PROC_COMPARE 3
.Os
.Sh NAME
.Nm proc_compare
.Nd compare two processes' interactivity
.Sh LIBRARY
.Lb libutil
.Sh SYNOPSIS
.In sys/sysctl.h
.Ft int
.Fn "proc_compare" "const struct kinfo_proc2 *p1" "const struct kinfo_lwp *l1" \
"const struct kinfo_proc2 *p2" "const struct kinfo_lwp *l2"
.Sh DESCRIPTION
The
.Fn proc_compare
function compares two processes that are on the same terminal for their
interactivity.
This means that the process returned is the one that has a better chance
being the active foreground process on that tty.
This algorithm is used in the kernel for
.Dv SIGINFO
reporting and in userland by
.Xr w 1 .
.Pp
The algorithm used is as follows:
.Bl -bullet -compact -offset indent
.It
If one of them is runnable, it is preferred.
.It
If both are runnable, the one with the largest CPU percent is preferred.
.It
In a CPU percent tie, the one started more recently wins.
.It
If none are runnable, and one of them is a zombie, the non-zombie is preferred
.It
If both are zombies, the one started more recently wins.
.It
If neither is a zombie, the one with the smaller sleep time wins.
.It
In a tie, and one is sleeping in non-interruptible sleep, prefer that one.
.It
If both are in the same state, the one started more recently is preferred.
.El
In all cases where the most recently started wins, if there was no winner,
the one with the largest PID wins.
.Sh RETURN VALUES
The
.Fn proc_compare
function returns
.Dv 0
if
.Fa p1
is to be preferred
and
.Dv 1
if
.Fa p2
is to be preferred.
.Sh SEE ALSO
.Xr w 1
.Sh HISTORY
The
.Fn proc_compare
was extracted from
.Pa src/sys/kern/tty.c
and
.Pa src/usr.bin/w/proc_compare.c
and merged in
.Nx 6.0 .

.Dt STRPCT 3
.Os
.Sh NAME
.Nm strpct ,
.Nm strspct
.Nd decimal percent formatters
.Sh LIBRARY
.Lb libutil
.Sh SYNOPSIS
.In util.h
.Ft char *
.Fn strpct "char *buf" "size_t bufsiz" "uintmax_t numerator" "uintmax_t denominator" "size_t precision"
.Ft char *
.Fn strspct "char *buf" "size_t bufsiz" "intmax_t numerator" "intmax_t denominator" "size_t precision"
.Sh DESCRIPTION
The
.Fn strpct
function formats the fraction represented by
.Fa numerator
and
.Fa denominator
into a percentage representation with given number of digits of
.Fa precision
without using floating point arithmetic.
.Sh RETURN VALUES
.Fn strpct
and
.Fn strspct
always return a pointer to a NUL-terminated (unless
.Fa buflen
is
.Dv 0 )
formatted string which
is placed in
.Fa buf
and is up to
.Fa buflen
characters.
If there was an overflow, the formatted string will reflect that precision
loss.
.Sh EXAMPLES
.Bd -literal -offset indent
strpct(buf, buflen, 1, 16, 3);
\(rA "6.250"
strpct(buf, buflen, 1, 2, 0);
\(rA "50"
.Ed
.Sh HISTORY
.Fn strpct
was originally implemented in
.Xr csh 1
for
.Nx 1.3 .
It printed into a static buffer, was not locale aware, handled
.Ft unsigned long
numbers, and printed a
.Dq %
at the end of the number.
Other programs such as
.Xr df 1
and
.Xr time 1
started using it.
.Fn strpct
and
.Fn strspct
appeared separately in libutil for
.Nx 6.0 .
