+.Sh NAME
+.Nm vlimit
+.Nd control maximum system resource consumption
+.Sh SYNOPSIS
+.Fd #include <sys/vlimit.h>
+.Fn vlimit resource value
+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by getrlimit(2).
+It is available from the compatibility library, libcompat.
+.Ef
+.Pp
+Limits the consumption by the current process and each process
+it creates to not individually exceed 
+.Fa value
+on the specified
+.Fa resource .
+If
+.Fa value
+is specified as \-1, then the current limit is returned and the
+limit is unchanged.
+The resources which are currently controllable are:
+.Bl -tag -width LIM_NORAISE
+.It Dv LIM_NORAISE
+A pseudo-limit; if set non-zero then the limits may not be raised.
+Only the super-user may remove the
+.Em noraise
+restriction.
+.It Dv LIM_CPU
+the maximum
+number of cpu-seconds to be used by each process
+.It Dv LIM_FSIZE
+the largest single file which can be created
+.It Dv LIM_DATA
+the maximum growth of the data+stack region via
+.Xr sbrk 2
+beyond the end of the program text
+.It Dv LIM_STACK
+the maximum
+size of the automatically-extended stack region
+.It Dv LIM_CORE
+the size of the largest core dump that will be created.
+.It Dv LIM_MAXRSS
+a soft limit for the amount of physical memory (in bytes) to be given
+to the program.  If memory is tight, the system will prefer to take memory
+from processes which are exceeding their declared
+.Dv LIM_MAXRSS.
+.El
+.Pp
+Because this information is stored in the per-process information
+this system call must be executed directly by the shell if it
+is to affect all future processes created by the shell;
+.Xr limit
+is thus a built-in command to
+.Xr csh 1 .
+.Pp
+The system refuses to extend the data or stack space when the limits
+would be exceeded in the normal way; a
+.Xr break 2
+call fails if the data space limit is reached, or the process is
+killed when the stack limit is reached (since the stack cannot be
+extended, there is no way to send a signal!).
+.Pp
+A file
+.Tn I/O
+operation which would create a file which is too large
+will cause a signal
+.Dv SIGXFSZ
+to be generated, this normally terminates
+the process, but may be caught.
+When the cpu time limit is exceeded, a signal
+.Dv SIGXCPU
+is sent to the
+offending process; to allow it time to process the signal it is
+given 5 seconds grace by raising the
+.Tn CPU
+time limit.
+.Sh SEE ALSO
+.Xr csh 1
+.Sh HISTORY
+The
+.Fn vlimit
+function appeared in

+.Fn vtimes "struct vtimes *par_vm" "struct vtimes *ch_vm"
+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by getrusage(2).
+It is available from the compatibility library, libcompat.
+.Ef
+.Pp
+The
+.Fn vtimes
+function
+returns accounting information for the current process and for
+the terminated child processes of the current
+process.  Either
+.Fa par_vm
+or 
+.Fa ch_vm
+or both may be 0, in which case only the information for the pointers
+which are non-zero is returned.
+.Pp
+After the call, each buffer contains information as defined by the
+contents of the include file
+.Pa /usr/include/sys/vtimes.h :
+.Bd -literal -offset indent
+struct vtimes {
+	int	vm_utime;	/* user time (*HZ) */

+	int	vm_oublk;	/* block writes */
+};
+.Ed
+.Pp
+The
+.Fa vm_utime
+and
+.Fa vm_stime
+fields give the user and system
+time respectively in 60ths of a second (or 50ths if that
+is the frequency of wall current in your locality.) The
+.Fa vm_idrss
+and
+.Fa vm_ixrss
+measure memory usage.  They are computed by integrating the number of
+memory pages in use each
+over
+.Tn CPU
+time.  They are reported as though computed
+discretely, adding the current memory usage (in 512 byte
+pages) each time the clock ticks.  If a process used 5 core
+pages over 1 cpu-second for its data and stack, then
+.Fa vm_idsrss
+would have the value 5*60, where
+.Fa vm_utime+vm_stime
+would be the 60.  
+The
+.Fa Vm_idsrss
+argument
+integrates data and stack segment
+usage, while
+.Fa vm_ixrss
+integrates text segment usage.
+The
+.Fa Vm_maxrss
+function
+reports the maximum instantaneous sum of the
+text+data+stack core-resident page count.
+.Pp
+The 
+.Fa vm_majflt
+field gives the number of page faults which
+resulted in disk activity; the
+.Fa vm_minflt
+field gives the
+number of page faults incurred in simulation of reference
+bits;
+.Fa vm_nswap
+is the number of swaps which occurred.  The
+number of file system input/output events are reported in
+.Fa vm_inblk
+and
+.Fa vm_oublk
+These numbers account only for real
+.Tn I/O ;
+data supplied by the caching mechanism is charged only
+to the first process to read or write the data.
