ulimit(2)		      System Calls Manual		     ulimit(2)

NAME
       ulimit -	get and	set user limits

SYNOPSIS
   Remarks
       The  ANSI  C "" construct denotes a variable length argument list whose
       optional	[or required] members are given	in the associated comment

DESCRIPTION
       provides	for control over process limits.   Available  values  for  cmd
       are:

	      Get the file size	limit of the process.
				  The limit is in units	of 512-byte blocks and
				  is inherited by child	processes.   Files  of
				  any  size  can be read.  The optional	second
				  argument is not used.

	      Set the file size	limit of the process to	the value
				  of the optional  second  argument  which  is
				  taken	 as  a long.  Any process can decrease
				  this limit, but only a process with  an  ef-
				  fective  user	 ID of super-user can increase
				  the limit.  Note  that  the  limit  must  be
				  specified in units of	512-byte blocks.

	      Get the maximum possible break value
				  (see brk(2)).	 Depending on system resources
				  such as swap space, this maximum  might  not
				  be attainable	at a given time.  The optional
				  second argument is not used.

ERRORS
       fails if	one or more of the following conditions	is true.

	      [EINVAL]	     cmd is not	in the correct range.

	      [EPERM]	     fails and the limit is  unchanged	if  a  process
			     with  an  effective user ID other than super-user
			     attempts to increase its file size	limit.

RETURN VALUE
       Upon successful completion, a non-negative value	is  returned.	Errors
       return a	-1, with set to	indicate the error.

SEE ALSO
       brk(2), write(2).
