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  the privilege 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.

   Security Restrictions
       Some  or  all of the actions associated with this system call require the privilege.  Processes owned by the superuser have this privilege.
       Processes owned by other users may have this privilege, depending on system configuration.  See privileges(5) for  more	information  about
       privileged access on systems that support fine-grained privileges.

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

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

	      cmd	     is not in the correct range.

	      fails and the limit is unchanged if a process
			     without the privilege attempts to increase its file size limit.
