-.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 brk 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 
-.Bx 4.2 .
-.Sh BUGS
-.Dv LIM_NORAISE
-no longer exists.
-
-This function has not yet been reimplemented.
